TikTok is a social network that could not be made by an American company, due to its complete disregard for free speech and embrace of censorship. This is a major part of its success, due to not allowing its network to deteriorate into culture wars and general unpleasant behaviour. I suspect any future social network much like TikTok will have exclusion as a major feature.
This is nonsense. All the social networks have things they will remove and ban your account for, from spam and CP upwards (Instagram and FB being notoriously touchy about sexuality). It seems that TikTok is heavier about politics than most, but censorship is not a boolean.
