    Who's selling the data is the far more serious issue here. Behind this is a remarkably well-structured syndicate. The supply chain looks something like this: consumer apps embed ad SDKs → those SDKs feed location signals into RTB ad exchanges → surveillance-oriented firms sit in the RTB pipeline and harvest bid request data even without winning auctions → that data flows to aggregators who don't have any direct relationship with consumers → and from there it's sold to government agencies, among others. The genius of this structure is that accountability dissolves at every layer. Each intermediary can claim they're just passing along "commercially available data." Nobody verifies whether consumers actually consented to their location data being collected and resold. The consent verification is always someone else's job. The real problem is that this data is buyable at all, by anyone, through an opaque multi-layered supply chain specifically designed so that no single entity bears responsibility for the end result.

      Apple and Google are facilitating the data sales

      Specifically, these big companies revenue share with app companies who in turn increase monetization via selling your private information, esp via free apps. In exchange for Apple etc super high app store rake percentage fees, they claim to run security vetting programs and ToS that vet who they do business with and tell users & courts that things are safe, even when they know they're not.

      It's not rocket science for phone OS's to figure out who these companies are and, as iOS / android os users already get tracked by apple/google/etc, triangulate to which apps are participating

        I'm game for throwing rocks at Apple and Google, but I don't get this one.

        > consumer apps embed ad SDKs → those SDKs feed location signals into RTB ad exchanges → surveillance-oriented firms sit in the RTB pipeline and harvest bid request data even without winning auctions

        Would you ban ad supported apps? Assuming the comment you're responding to is realistic, I'm not sure how the OS is to blame.

        • godelski31 minutes ago
          Neither big players have refined enough permissions. These set users up for giving away more data than they think.

          Maybe one clear example is needing a permission once for setup and then it remaining persistent.

          An easy demonstration is just looking at what Graphene has done. It's open source and you wana say Google can't protect their users better? Certainly Graphene has some advanced features but not everything can be dismissed so easily. Besides, just throw advanced features behind a hidden menu (which they already have!). There's no reason you can't many most users happy while also catering to power users (they'll always complain, but that's their job)

          There's no need to ban ad supported apps when you can just ban the practice of using ads targeting users based on individual characteristics.

        • hedoraan hour ago
          Apple supposedly does this with the privacy report cards.

          However, I'd be shocked if a cursory audit comparing SDKs embedded in apps and disclosed data sales showed they were effectively enforcing anything at all.

        • lmeyerov2 hours ago
          You can trace the big players

          If Google & Apple & friends refused to take a rake and opened distribution, then I'd agree, net neutrality etc, not their problem

          But they own so much, and so deep into the pipeline, and explain their fees to courts because "security"... and then don't do investigations. They employ some of the best security analysts in the world and have $10-30B/yr revenue tied to just the app store fees, so they very much can take a big bite out of this if they wanted.

            I'll never not be impressed by how many people will defend trillion dollar organizations and say that things are too expensive. Especially when open source projects (including forks!) implement such features.

            I'm completely with you, they could do these things if they wanted to. They have the money. They have the manpower. It is just a matter of priority. And we need to be honest, they're spending larger amounts on slop than actual fixes or even making their products better (for the user).

          Yes, I absolutely would. Advertisements are a scourge upon people's wellbeing on top of being ugly and intrusive.

                  Do people really still think advertising has a legitimate function?

                  Really these days it's 95% psychological manipulation to get people to buy inferior quality stuff they don't need. And 5% of people actually finding what they're looking for.

                  Don't forget, most advertising can work fine in a "pull" mode. I need something so I go out and look for it. These days something like Google (not ideal because results also manipulated by the highest bidder). Or I look for dedicated forums or a subreddit for real people's experiences. In the old days it would have been yellow pages or ask a friend.

        If I have a free app that hits location services on the device and I sell this data, how does Apple and Google make money from me?
      • GeekyBear2 hours ago
        Apple doesn't even allow apps to know whose device they are running on without the user's explicit opt-in permission.

        Just as importantly, apps aren't allowed to remove functionality if the user says no.

        You need additional permissions to do things like access location data or scan local networks for device fingerprinting.

        • quickthoughts36 minutes ago
          It's everyone. Especially google, but all the big tech companies play in the same pool. Amazon, Google, Apple, Meta etc make money selling ads, which ultimate enables the tools that result data harvesting from everyone across the internet. I wrote a little data investigation [1] (mostly finished) that show cases how every major news organization across the globe I scanned had some level of data collection integrated. This is just one industry, but its important (as it connects back to the incentives these media organizations have, which is to make money by selling ads at any cost). The eff also released an angle in how the bidding process to buy ads is itself a massive privacy nightmare[2]

            Yeah, but unlike facebook, they weren't just caught making videos of people having sex then paying people to watch the videos.

            Also, unlike facebook, they also weren't just caught running a dark money lobbyist network with the goal of forcing more collection of minors' private information.

              facebook is evil for many different reasons, but for a government looking to spy on its own citizens cloudflare is much more attractive target. That said, I have no doubt that they're collecting copious amounts of data from both companies, either by sale or by force.

        • lmeyerovan hour ago
          There are plenty of bad actors

          The interesting part is Google & Apple, as part of explaining to courts why their large app store fees are legit and not proof of monopoly positions, hid behind the security argument that they need to be the clearing house of what software runs on the devices. Except... they've knowingly punted on this one for 10+ years.

          I would 100% agree that losing privacy through any utility-level carrier (credit cards, phone, OS provider, etc) should be default disallowed, and any opt-ins have a clear transparency mode with easy opt-out. At least two areas the US can learn from the EU on digital policy is digital marketplaces and consumer privacy protection, and this topic is at the intersection of both.

    • samrus3 hours ago
      I think the pipeline needs to be plugged at both ends. We shouldnt allow this data to be sold without express consent. And we shouldnt allow the government to purchase this sort of data regardless of consent, protected under the 4th amendment. unless, iguess, express consent is given to be used by the government for investigative purposes, which no one would give since they dont have to under the 5th amendment

        Don't forget the initial collection. Nobody is forcing these app developer to link the HarvestCustomerLocation.lib module to their app. They're doing it voluntarily, likely financially incentivized. Don't let them off the hook.

        > And we shouldnt allow the government to purchase this sort of data regardless of consent

        Fine, we'll force companies to allow a small little box to be added to their data center. Don't worry about what it does, but you cannot disconnect network/power to it once it is installed. Once it is operational, you'll no longer need to think about it ever again, and we recommend that you don't. You should also not talk about this box to users/customers/clients. In fact, you'd be better off if you didn't talk to your employees about it either.

        • autoexec2 hours ago
          There's no reason to think that this doesn't regularly happen by at least one three letter agency. It's something they've done for a very long time (https://en.wikipedia.org/wiki/Room_641A). They were willing and able to secretly redirect every last bit of data going over AT&Ts backbone into their systems back in 2003 you can bet that they have at least that much capability in place today.
          • dylan60438 minutes ago
            It's why FB decided to encrypt in transit data moving internally between data centers. I'm guessing some TLAs were none too pleased with that. Then again, maybe they suggested a particular encryption to use so they can say they are encrypting yet not slowing down the intake either????

            Especially after Snowden, if anyone does not think the US govt TLAs are trying to read every bit that crosses a wire, then they are just deluding themselves. Even before Snowden, Echelon was known for telephonic intercepts. It didn't take much imagination to take it further for internet traffic. Snowden just removed the need for imagination.

        I think sale and purchase are too hard to police. Possession of data should be illegal, with a level of statutory damages that invites litigation.

        The greatest part of reading HN is finding out that my distrust of apps and their developers is not weird. It does make me question my abilities as a dev for refusing to partake in these reindeer games. Clearly, I am not the right type of person to do well in big tech.
        • autoexecan hour ago
          The problem is that it is weird. It's the smart/right thing to do, but countless people mindlessly install whatever they're told to install or whatever looks fun. We hand mobile devices over to children who have no idea why they shouldn't, but honestly many adults are just as ignorant and trusting.

          Most people I've spoken with are either thinking "Apple/Google/Government would never allow apps to do something like that!" or they think "Everyone is already doing it so why bother trying to fight it. I'd only be inconveniencing myself for nothing"

      Everyone who has it is selling that info, and nearly everyone who collects it is selling it. Until there are laws that actually protect us, we should stop giving companies our location data every chance we get and push for laws that prevent it from being unnecessarily collected in the first place.

      • roysting40 minutes ago
        "FBI is buying location data to track US citizens" ... "Until there are laws that actually protect us"

        I don't see how we overcome that massive hurdle. It's not like those who ostensibly make the laws don't know and approve, and probably intentionally implemented that.

        We now have full scale mass tracking and surveillance of the kind no one pre-9/11 would believe would have been allowed to exist in the form of the Flock cameras (of course it was an enemy Brit implementing surveillance in the USA) making anonymity quite literally as challenging as Winston Smith trying to move around without being detected to meet his love interest.

        How are we going to get the de facto tyrants in the government to pass laws that materially disempower them by being unable to mass surveil everyone at any given time if they don't like what you are saying or thinking?

        The problem with all the naysayers for all those decades is that once you have given up control over your own life and you have given away your rights protected by the Constitution, your enemies in the government are unlikely to simply give them back because you ask nicely. In fact, they will most likely aggressively move against anyone that even suggests that you nicely ask for your rights back.

        Explicitly outlawing the practice is good, but since they've already been participating in the violation of our rights and knowingly profiting from it there should be consequences.

        I'd be perfectly fine with going after companies that sell data to the government, but I don't think it would be fair to go after companies who were forced to hand data over unwillingly, even if they didn't inform the public it was going on out of fear of reproductions.

      And it’s working precisely as designed

      For example you can have a truthful statement: “all of the apps that you have are constantly spying on you”

      And the rejoinder is “ any given app is not specifically selling my data to specifically the FBI and so therefore it is not spying”

      To which the response would be: “that is correct however the aggregate data is bundled and sold off to specifically the FBI or intelligence agencies and so there cannot be a logical differentiation between apps.”

      By that point the person has downloaded another rewards app and added their drivers license to it.

    I'd really like to just have legislation to treat location data like audio or video under wiretapping provisions. If you collect my location info and convey it to a third party without my consent or a reasonable good-faith belief that I would consent, that ought to be treated similarly to recording without consent.

    And consent needs to be granted explicitly for each party that might get access to my location, you can't just get blanket consent to sell my location to anyone, especially not with real-time identifiable location data.

          • Jtsummers5 hours ago
            Fear of packing the Supreme Court is a fear of something that the current parties have not done. There's an 1869 law that would have to be changed to pack it since that law sets the number of justices to nine. After that, they'd have to get their justices confirmed.

            • Jtsummers5 hours ago
              When people talk about packing the Supreme Court they're talking about adding justices so that one side (the one doing the nominating and appointing) gets a majority. It's not about filling vacancies (or blocking filling vacancies) to reach the current limit of nine justices.

        • cael4505 hours ago
          There is nothing sacred about the number of Supreme Court justices, and historically there was one for each circuit, which is not the case now.

          But the truth is, Democrats can win every single election this year and in 2028 and they would not be allowed to govern by this Supreme Court, which has chosen over and over again to overturn precedent and sow chaos.

          Unfortunately, to arrest the slide into right-wing authoritarianism, you have to adopt their tactics sometimes.

          But you don’t have anything to worry about. The democrats aren’t going to do any of this, and we’ll be in an even worse state in 2032.

        • CSSer5 hours ago
          That's not "kinda the same" at all. You can feel however you like about the strategy, but the constitution specifically doesn't elaborate on how many justices make up the supreme court. Article III simply states the following:

          > The judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish.

          There is a huge gulf between ignoring standing law or a supreme court ruling and ignoring precedent. One involves choosing not to acknowledge i.e. disobeying, an authority, and the other involves choosing to act differently than has generally been expected in the past. Moreover, at least in recent history, it's primarily the Republicans who began the practice of ignoring precedent, long before our slow descent into where we are now: blatantly flaunting the law. See Merrick Garland's ignored nomination or the house's recent ludicrous delay of swearing in an elected representative for just two easy examples of this.

          I mean none of this in any partisan fashion. It's simply a matter of fact. The idea that the GOP and the Democratic parties somehow engage in the same level or kind of antics and are thus deserving of the same level of nihilistic apathy as some kind of moderate position is charitably tragically misinformed.

    That's the job of the FBI - to investigate domestic crimes. But, why do private organizations so willingly participate in the tracking ecosystem? I suppose they're in the, "you have nothing to worry about if you're not doing anything illegal" camp! Hopefully they understand that they have the most to lose.
    • wmf5 hours ago
      It's just business. Buy (your data) for a dollar, sell for two. It's all legal and the data brokers are mostly unknown or already-hated companies so I'd say they have nothing to lose.

          Differential identification means you can be singled out based on profiles. Even if you don't have any accounts, big tech companies still have shadow profiles, and those shadow profiles can be linked to your offline identity, such that everything you've done that's been recorded, and everything you've done in (temporal, physical, or digital) proximity to other people who do have accounts results in a record of activities.

          Sure, you can get a burner, but you have to make sure you never use it anywhere near anyone you know, that the sim is obtained anonymously, that you're never imaged by any of the ubiquitous cameras, etc. Merely having it powered on provides enough metadata to establish a shadow profile, and it's nearly impossible for a person to secure two separate identities. There's also the superman problem - the burner phone would only ever appear when anonymars is missing, and vice versa, creating a real and exploitable pattern if anyone like the FBI wanted to root around in your life. All they'd have to do is query which shadow profiles match the temporal gaps correlated with your disappearance from tracking.

          There's really no escaping it. The only fix is legislation - outright banning mass surveillance, with lethal corporate penalties and long prison terms for C-Suite responsible for violations. Short of that, we live in a world that is implicitly compromised and insecure unless you have nation state level resources.

            This is nonsense. By your logic, people go 'missing' any time they are not using a computer, whether they're reading a book, in the shower, or asleep in bed.

        What if an investigation is based on finding the same specific people near another specific person that they're tracking, but they only know about the one person, not the others.

        And by doing this they stop a terror attack?

        One more thought - if they buy just data for specific people related to an investigation, the seller of the data is tipped off. If they just buy all the data, then there is no potential tip-off to the target.

        • themafia4 hours ago
          You get a "geofence warrant." They exist and are ubiquitous. You then go to Google or any other provider and you demand the data for a specific location in a specific time window. You then use the data to capture criminals. Any other data would not meet the standards of evidence and probably couldn't be used in court anyways. It's only function is for "parallel construction."

          Then again, what I _really_ want is for the FBI to prevent crime. If their only solution is to let crime happen and then use a giant dragnet to put people in jail then they are less than worthless... they are actively dangerous to democracy.

      Because it makes them money and that's literally the only thing they care about. They'd do anything for money and the only reason they ever don't do something is because it either wouldn't make them money at all, or it would cost them more money than they'd make.

      For profit organizations are legally required to maximize shareholder value. Many of them will abuse the spirit of the law in order to squeeze profits where others won’t.

      The FBI is violating the spirit and original intent of the 4A by creating an entire industry out of the “3rd party doctrine” bypass to the 4A. That doctrine was whole cloth created by SCOTUS and Congress has been too happy to avoid credit or blame for it to not enshrine it in statute.

      Lemme give you an example.

      Many retail sites have a "find a nearby" store function. They often outsource this to a third party...for something as silly as geolocation and geographical lookups. This third party is the one that offers its services for a discount but also siphons up your location data to sell.

      Enough location data becomes effectively unique: There is likely only one phone in the world that averages over X nighttime hours in my apartment-complex and averages over Y workday-hours in the the same office block where I work.

      That kind of pattern can be used to determine that two or more different app-identities are the same person, and anybody buying that data has a strong incentive to try it.

      Fingerprinting devices once you’re installed on them isn’t much harder than doing so in a web browser.

      Have Instagram installed on your phone? Great, now every Meta-owned app _or advertiser running on their platform_ has a pretty good shot at identifying you based on IP, location, app usage, etc.

      There is a ton of signal about identity available just by virtue of running alongside other apps. Screen size, OS version, and IP are pretty good proxies for unique identity, especially if all you care about is _probable_ matches.

      Yes. But AFAIK, not an unconstitutional one. Wyden agrees with you:

      > Wyden said buying information on Americans without obtaining a warrant was an “outrageous end-run around the Fourth Amendment,”

      America needs privacy laws for this reason (or an amendment, but good luck). Vote when November rolls around; the other piece is finding Democrats that will take an actual stance on privacy closer to Wyden's.

    In the US we live in a bizarre world of dual expectations.

    The government is supposed to follow the law, be accountable, transparent, and must operate within a constrained, circumscribed zone of activity which is debated and discussed. That's at least how it's supposed to work.

    Private companies are understood as amoral sharks who have no obligation to do anything other than operate in their narrowest self-interest, and the law is used as a club to beat them back from what they so clearly want to do, and will do if at all possible. They are unaccountable to anything other than the legal system and their share price. Suggesting that they might have any further obligation is tantamount to questioning whether capitalism should exist. It happens all the time on HN.

    So of course the FBI would like to keep their hands mostly clean by having one of those accepted-to-be-horrible companies gather this data and then buy the resulting trove.

    • array_key_first3 hours ago
      A lot of them don't know they're doing it. The tracking itself is embedded in dependencies of dependencies. SDKs you add for legitimate purposes. Along the way it's sent from platform to platform. Analytics, add targets, and eventually data brokers. Data brokers then sell it to other data brokers or the government.

      If you're lucky, it's pseudo-anonymous. Of course it's actually not - aggregated location data is inherently not anonymous.

    • jshier3 hours ago
      What would you like them to do? They already force apps to ask for permission, give user control over when the app can even access the location (including just once), tell the user when the app has been accessing the location repeatedly over time, and allow the user the shut off location services for each app individually whenever they want. So aside from shutting off more and more possible sideband sources of location information, what else are they supposed to do?

      Unless you're saying Apple is selling the location information they may have directly?

      • jshier3 hours ago
        Answering my own question, they need a way for users to grant location permission only to the primary app and not any of its dependencies, as once you grant it, it's available to all code in the app. It would be great if there was some way to separate those.

        They could also better enable network traffic inspection on device, so we could tell where data is going. LittleSnitch on iOS would be great.

        • betaby2 hours ago
          IP is often enough to correlate things. LittleSnich or whatever is no help - oftentimes data is collected by the app/site directly, and then funneled to various systems via kafka-like brokers. In this case you always have only cobbections to something like cool-application-domain.au

      Kinda reminds me of when I saw footage online of a group of teens raiding a 7/11 store -- maybe during the BLM riots --, and a top comment was "heh, come try that in Texas ;)". Fantasizing, of course, that Texas has a unique bulwark against that behavior, probably having to do with gun ownership.

      And then it turns out the video took place in Dallas.

      We like to think there are all these barriers to bad things happening where we live. "I'm sure someone (not me) would stop that." But it turns out there isn't as much bulwark as we think. Or we're the bulwark, so if it isn't us, then there is nobody else.

        It’s that sort of behavior— groups of perpetrators committing crimes— that allow people to justify enhanced surveillance tactics.
