Like on the one hand, I obviously think that if this is a frequent behavior on commonly used chatbots, yes that's a problem. But if you have tens of millions of people talking to chatbots, I think it's almost inevitable that somebody is going to take something the bot says as a justification to do something wrong/illegal (in the same way that some crazy person is going to say a celebrity is in love with them, or that some crazy person will use a kitchen knife as a murder implement).
For now I think the world is a much better place with more competition in the AI market rather than fear of a lawsuit stifling smaller players.
