When I go to a social event, I expect the organizers to keep people out who are only there to start trouble, and do harm. Requiring people tell the truth and not lie, isn't trying to "control them". Republicans seem to have a real problem with that one simple requirement - to tell the truth.
I have noted that FaceBook is allowing all manner of snake oil salespeople and scammers to advertise on their platform. It's gotten so bad that at this point, I won't buy anything being advertised on FaceBook because I assume they're not legit. Most of my friends say the same thing.
FaceBook has lost all of its legitimate advertizing revenues because legitimate companies are pulling their ads and for the same reason.
But keep thinking that "freedom of speech" has anything to do with their "hands off" policies.
