Equating private with public messaging is ridiculous. Not sure how laws are in the US, but when doing support here in germany we had to have private in-game messages reported by a participant before we were even allowed to look at them. The company obviously had a much easier time shaping the atmosphere in the public forum.

Also while ensuring those tools can never be used for "evil" is unreasonable, we should expect dominant players to do what they can or at least not do a lot worse than everyone else. Are you arguing Parler tried to moderate as much as others?
