-No porn on Facebook is the equivalent to no nudity allowed at the mall.
-Banning users is the equivalent of kicking a person out of the mall.
-Censoring messages is the equivalent of... uh.. gagging a person just before they can say something you didn't want them to say.
-Direct messaging people or groups is the equivalent of talking to your friends, while an anonymous person videotapes and listens without really letting you know they're doing that.
-Posting a status is the equivalent of shouting what you're feeling or thinking to nobody in particular
-Facebook curating newsfeeds is the equivalent of putting you in a room and showing videos of the things your friends are shouting, intermittently throwing in advertisements, and just kind of letting you believe that what you're seeing is real and unadulterated.
Point is, if you look at Facebook like a physical establishment, it's a pretty weird place.
But as long as people continue to recognize that censorship and surveillance are not cool, they will continue to complain to the groups who engage in it, and constantly be on the lookout for better alternatives.
I personally recommend Snapchat for un-surveilled interaction with friends, Hacker News for news with uncensored commentary, and LinkedIn to stay connected with people. And I'm glad that there are reasonable alternatives to all of these
