Okay, what concrete harms has Meta done with this information? At best you have some creeps using it to stalk their exes, which is bad, but a far cry from the AI takeover scenario implied by OP.

They target toxic ads at people with poor mental health who are especially vulnerable. They do this intentionally because it's profitable.

There's plenty of reporting on this if you care to look it up. It "works" too. Spending more time on Meta products results in having more body issues, poor self esteem, and suicidal ideations.

But if I remember right you work for a big ad tech company and have previously gone to the mat to defend such practices, so I suspect you aren't genuinely asking.

I haven't implied an AI takeover, this data will be repackaged into a product for military/intelligence, political applications, insurance companies that can charge you more because they know you're willing to pay, and many more.

These things already exist and happen, it's about the data getting better and not having to build tools to query it and make projections, since you can just type a query into a box even if you're not a data scientist.
