Directed negligence isn't much better, especially morally.

You always have liability. If you put something there you tell the court that you see the problem and are trying to prevent it. It often becomes easier to get out of liability if you can show the courts you did your best to prevent this. Courts don't like it when someone is blatantly unaware of things - ignorance is not a defense if "a reasonable person" would be aware of it. If this was the first AI in 2022 you could say "we never thought about that" and maybe get by, but by 2025 you need to tell the court "we are aware of the issue, and here is why we think we had reasonable protections that the user got around".

See a lawyer for legal details of course.

They already censor Grok when it suits them.
