I don't think the issue here is whether FaceBook is acting illegally, but whether it is acting responsibly, or just enshittifying society for it's own benefit.

Note incidentally that "free speech" doesn't mean you can say what you like. Yes, you can go out in public and swear and engage in hate speech - all legal - but for example you can't incite others to commit crimes, cross over into disorderly conduct, shout "fire" in a theater, etc.
