I can kind of see what you are trying to say, but I don’t really agree with your conclusion.

I’d make the distinction that free climbing, while dangerous, is a recreational activity. I can reasonably conceive of people watching that for entertainment. There also isn’t anything morally questionable about it.

On the face of it, I don’t think you could reasonably argue that torture is a pastime.

All of that aside, torture is against international law. It is illegal in all circumstances.

From the United Nation Convention Against Torture:

“No exceptional circumstances whatsoever may be invoked as a justification for torture.”

For that reason, I would say the platform did have an obligation to de-platform it.

Arguably, the police should probably have put a stop to it as well.

I’d argue the main difference is that it involves a crime.

I’m not completely sure that torture itself constitutes a crime (though I’d be surprised if it wasn’t), but manslaughter/murder is. With few exceptions for medically assisted death, killing someone is a major crime. Presumably, we don’t want to promote people profiting from extreme suffering and death.

I also think there is a time and place for censorship (ex CSAM).

“Objectionable” is a subjective term, but “illegal“ is not.

Here’s an interesting podcast on the topic of lab meat that shows just how much grandstanding this “fight” really is. https://open.spotify.com/episode/4yCKSioorfxTL6x7PaunOR?si=fCHOyvmgSXqITX9x7_6GxA

TLDR: they’re banning a product that isn’t even commercially available to the public yet.
