I mean, Germany bans nazi imagery in media. Many countries ban false advertising. A number consider it not ok to discriminate against people based on their characteristics. Fringe health statements are often disallowed. TikTok just got hit with a speech case about a girl hanging herself to death because of a video.
Government moderates speech all the time, and yes, there's obviously grey areas and opportunities for abuse with those systems. I want to see the examples. Not someone grinding an axe with "the opposition"... show me what was not allowed.
