It did come from Claude, though, not Anthropic.

If I were Anthropic I would have some kind of TOS restriction saying that you can't use their trademark to represent what you use their API to enable. It's just inappropriate. Even if you are a full anti-AI activist, it seems clear that the blame for specific things 'Claude' does in response to a deliberate prompt should fall on the person(s) operating it, and as such they shouldn't be allowed to make it appear that this is what Anthropic designed Claude to do.

Anthropic sees Claude as having its own identity, and wants to foster that independence. This behavior is already aligned with Claude's station.
