You're not wrong, but the problem for Meta is that this, along with their other fine for mental harm is setting a precedence.

This fine is somewhat larger, at $375 million, but the other one (https://www.msn.com/en-us/health/other/meta-and-youtube-fine...) basically open the gates for millions of people suing.

Sadly I don't think it's enough for Meta to change, because they have no business model if they are forced to be serious about online safety. That's probably also why they are pushing so hard for age verification, make safety a problem for someone else.
