Any form of censorship will decrease the value of social media sites in the long term. Look at twitter, there's been a shift towards gab.ai because many tweeters felt that there was too much censorship. People have complianed recently about reddit. I suspect it will happen to facebook too. Steemit and platforms like it, that don't censor, will be in place to hover up those dissatisfied users.
Let the market decide what is valuable.
