> this is about US culture, not US government or law
But these things do not exist in a vacuum.
Ask anybody working on the tech and legal ends of the adult industry and you will hear quite horrific stories about having to jump through so many hoops just for finding a payment provider.
For a while, these used to be www dominating issues, and how they were dealt with in the US, often ended up being the de-facto global standard.
A very recent and relevant example for this is footage out of the Syrian Civil War on platforms like Twitter and YouTube.
Over these past years, whole swats of videos have disappeared on the basis of being tagged as "terrorist propaganda" [0]
In a very similar vein how "Napalm Girl" ended up getting censored as child pornography [1].
By now even Reddit has learned to "selectively forget", as all undeleting/uncensoring sites that used to work, have stopped working.
Just because it's not some US government agency playing the censor, but rather the US government pressuring US companies into self-censorship, doesn't make this kind of censorship any less real in its overall impact.
