Facebook, as a community is fine.

The evil lies in the feed. All the standard addiction techniques are present. All the engineering to promote "engagement" is actually basically addiction. And the attempts to show you want you want have a strong tendency to show you more extreme versions of anything you previously watched. It's very, very easy for it to lead you down a rabbit hole into extremist territory. It's inherent in any such prediction algorithm unless somehow the selector understands to bias away from extremism.
