> swaths of free speech

Which is very cultural dependent as well. "Not being able to log in on TikTok if you are under 16" is not "preventing free speech". And "having no access to pornhub" is not preventing free speech either. Edit: TBC: this is not me defending these laws or rules.

E.g. Freedom of speech in the US, is rather narrow. It merely states you may "speak, write, and print with freedom" but not that you may do so anywhere, on any platform, on private property. It doesn't state that such speech, writings or printings must reach everyone.

The UNHCR article 19 goes further, though. But it doesn't automatically apply to the US. https://en.wikipedia.org/wiki/Universal_Declaration_of_Human... It includes `... and to seek, receive and impart information and ideas through any media and regardless of frontiers`.

And all these only apply to governments. Many of the examples you mention, aren't government-imposed but imposed by private entities (who, granted, often pre-emptively self-censor). E.g. certain words used on Instagram or in Yourube videos will hurt monetization, or will cause it's discovery or promotion to severely degrade; which is why people use phrases like "unalived". So let's not pretend the US is any good in this.

Dutch culture used to be rather free with nudity in movies and on TV. Every Dutch movie from before the era of US streaming services had at least a pair of naked boobies bouncing around. But this, and in it's wake the entire culture has become more prude-ish. A form of cultural colonialism by the US. Not terrible, but a good example of private companies imposing self-censorship even in places where it really is not needed. IANAL, but I'm quite certain youtube would be allowed to run videos with nudity just fine in most of (nothern?) Europe. But they don't.
