America is partly guilty, but TikTok censorship is a big part of the younger generation's tendency toward self censorship.
There's no such censorship on TikTok, it's entirely groupthink based on people saying "when I use that word my video is seen less so therefore it's being censored".
Youtube is a lot more guilty of it though, as well as demonetizing.
As much as I personally dislike TikTok, I don't think it is fair to it: cultural willingness for more sensor sheep on Internet started years before TikTok's popularity in the west.
