Given the nature of large organisations, and that they are obviously important vectors for anyone who desires to attack whoever they please, I assume that all the Big Tech companies have not only US government agents embedded inside them, but also non-US government agents and criminal agents also, and all of them will be attempting to exploit whatever they can including Mythos (and everything else) for gain.

However, the rate of change we're currently seeing says that before 2030 everyone will be able to access this kind of power on a local model hosted on their own phone, which means it goes from being "the NSA are using it to hack BYD, while China is using it to hack Premier Election Solutions' voting machines" becomes "local drug dealer hacks all local surveillance cameras[0] they walk past, replaces footage with deepfake of someone else so they can't get recognised in footage".

Ideally, things like Mythos close the security vulnerabilities. I am deeply cynical that this will be successful, because of all the times a boss has demanded special privileges to the detriment of security (famously both Hillary Clinton and Donald Trump, the latter in multiple different ways).
