To treat the machine as a machine: it's like complaining that cars are dangerous because someone deliberately drove into a concrete wall. Misusing a product with the specific intent of causing yourself harm doesn't necessarily remove all liability from the manufacturer, but it radically changes the burden of responsibility.
Another is that this is a new and poorly understood (by the public at least) technology that giant corporations make available to minors. In ChatGPT's case, they require parental consent, although I have no idea how well they enforce that.
But I also don't think the manufacturer is solely responsible, and to be honest I'm not that interested in assigning blame, just keen that lessons are learned.
