Facebook is old and not very good at the content moderation / censorship balance. Yep.
Seems like a lot of people want to be edgy and hate facebook without ideas on how to do things better (unless those ideas are pretty extreme censorship favoring a specific ideology).
Facebook is doing somewhat of a bad job but still people are trying to use it as a scapegoat for perfectly normal shitty human behavior which finds a way to exist regardless.
