How Openclaw works is wildly irrelevant. The facts are that there is a human out there who did something to configure some AI bot in such a way that it could, and did, publish a hit piece on someone. That human is, therefore, responsible for that hit piece - not the AI bot, the person.
There's no level of abstraction here that removes culpability from humans; you can say "Oops, I didn't know it would do that", but you can't say "it's nothing to do with me, it was the bot that did it!" - and that's how too many people are talking about it.
So yeah, if you're leaving a bot running somewhere, configured in such a way that it can do damage to something, and it does, then that's on you. If you don't want to risk that responsibility then don't run the bot, or lock it down more so it can't go causing problems.
I don't buy the "well if I don't give it free reign to do anything and leave it unmonitored then I can't use it for what I want" - then great, the answer is that you can't use it for what you want. Use it for something else or not at all.
