Sorry, but the tankies who think nothing bad has ever been done in the name of communism are just as foolish as the InfoWars junkies screaming about chem-trails.
People don't care cuz they don't think that it'll ever be forced on them "I don't do anything wrong why should I care?".
Plus they don't think much about the gravity of the situation, John Oliver did a nice take on this in the Snowden interview episode.
I think a better step for twitter would to be decentralize the admin powers to its users with better blocking options (blocking on chosen words, regex for racist memes?), but in this case there will be the possibility that you're just building more echo chambers.

It is supposed to, if you add fear mongering to it. Dictators usually believe in it, that's why they try to control every news outlet or public space there is and spread their propaganda
