Really? There's so much information about how Meta targeted children with addictive design patterns. They paid the fine, and profited in the meantime. Do you really think they have any reason not to do the same in the future?

They will use it for nefarious but "legal" purposes - however - they have decades of experience handling such data and keeping it "safe" from "illegal" purposes.

I think an $18 billion dollar fine implies that they broke a law or two.
