Social media is a forum for people to complain about the problems they face, if you don’t like that the solution is not to censor the messenger but to fix the problems.
As someone who grew up in the UK I can tell you that the elitist mindset of the UK is a huge part of their problem: only the elite are capable sophisticated right-think, all others are wrong-thinking simpletons and must be silenced for their own safety. The BBC is a huge part of the problem as it is inevitably pro-government but trades off a strong image of neutrality, to the extent that it regularly misleads the public and they lap it up.
IMHO, there's nothing authoritarian about either editors or social media. It only becomes authoritarian when they intentionally align with a central political authority.
I don't support censorship. But increasing the accuracy of the information most people are getting is a difficult problem to solve.
