It's not just limited to government oversight. This is a broader issue with the way that these words—like “racist” and all the other epithets you can think of—are used in the social media context. It's completely arbitrary in a lot of cases. One day, it's okay to say something. The next day, it's not okay to say something.
I would suggest that it's not even just a function of centralization and government bureaucracies, although removing the public oversight creates additional risks, perhaps. Just the way that these things change for no apparent reason presents, I think, significant risks to, say, banning hate speech. What counts as hate speech can change from one day to the next.
