right, the thread you responded to is asking why there hasn't been a parallel criminal suit

The answer is because US government finds AI more useful than some hosting service for pirated media. It's kinda boring, but it's as simple as that.

Maybe because Anthropic isn't actively facilitating copyright infringement?..

How is not? Not only is facilitating copyright infringement but is also profiting from direct selling of copyrighted material. “Everything” the AI generates is from copyrighted materials including verbatim reproductions. Sora was even more obvious.
