Nudity is banned on television, youtube, facebook, twitch, and any public place in the US. None of those had significant outcry when it was banned, and people bat an eye so little at that status quo that I apparently had to write this comment to remind you.
Please feel free to point us to the evidence of HN howling with outrage about the chilling consequences of our digital overlords succumbing to activist and advertiser presssure to ban porn (and presumed porn) on their platforms. When Tumblr banned porn, the general reaction was "lol, they're not going to have any audience left" and the one person that raised it as a speech violation (as opposed to a bit of a shame for kinky people) was downvoted to nothingness.[1]
Compare and contrast with how this thread, instead of focusing on "lol, algorithms and context!" has turned into questioning whether the real problem is advertisers signalling they don't want to attach their brand to racist videos (and let's not get started on how angry much of HN was when companies decided to manually enforce policies against hate speech). It's difficult to conclude that most US "free speech" advocates don't believe that banning [perceived] racial hatred is somehow more dangerous to humanity than banning [perceived] adult content (which parallels Supreme Court rulings on what speech does and doesn't deserve protection). Given the respective consequences of racial hatred and pornography, I see this simultaneous presumption in favour of the former and against the latter as very hard to justify.
IME few creators on youtube are willing to risk their channels by taking any risks in that regard.
For example, I'm told the character creator in 'Cyberpunk 2077' offers adjustable penis size - but many streamers and reviewers won't risk showing it. Even comedy channels that love creating zany characters.
After all, would you trust Youtube to detect whether nudity is pornographic context, when they can't even tell if 'white threatens black' is in a chess context?
