I wonder if there's any way of getting it into people's heads that they need to maintain their own data under their own care, but I fear the big platforms sink way too much money into propaganda to convince people to continue trusting them.
The sandwich is yours and you should be able to trust it, but you shouldn't rely on the expectation that the same guy will be handing out sandwiches for free at the same corner every day. They might just not be there one day, or simply tell you "I don't like your face, you don't get sandwiches anymore".
Facebook is the sandwich guy, as are google, microsoft, etc. Enjoy the free sandwiches, but plan in a way where you wouldn't just starve without them.
Maybe with AI at some point, we 'll get a consumer AI box with enough intelligence, compute, storage and low price that it can handle those things without putting mental load on the consumer to maintaint and or set it up.
If you want the convenience of having your stuff stored in the cloud without backup, which is already asking for trouble, then yea, that's a luxury that doesn't come for free.
That being said, one person can easily self-host for a whole family, friend group or entire neighborhood.
And your response gets even dumber with bringing up AI. I won't bother explaining why, it should be self-evident if you stop and think for a second about the AI business model.
If they have to "maintain their own data under their own care" and it's inconvenient, they'll prefer the convenient option, even if it means ocassionally losing their stuff or lacking privacy.
