It is difficult for anybody to stand for their values in these conditions. China does not pretend to be a politically free society - but I believe I'd have a better shot freely talking about Western politics on a Chinese service than an American internet service today.
People with my opinions are not a threat to the CCP - so I would be left alone. The number of times I've been banned for speaking simple opinions that just don't conform to the consensus of the hour is more than I can count. All from American web services. Even Sam Altman - who owns some of those services has said the same. It's the synchronization that is causing all the overreactions and underreactions to events.

Ignoring governments - who can have valid political and strategic reasons to be censors - the social media censorship is more serious because it is operating at the social layer - all those capillaries. Social consensus enforcement touches more people in everyday life.
