To be fair, Anthropic didn't say that either. Merely that autonomous weapons without a HITL aren't currently within Claude's capabilities; it isn't a moral stance so much as a pragmatic one. (The domestic surveillance point, on the other hand, is an ethical stance.)
Their rational was pragmatic. But they specifically said that they didn't agree to let the DoD create fully automatic weapons using their technology. I'll bet 10:1 you won't ever hear Sam Altman say that. He doesn't even imply it today.
Agreed, the moral stance is saying no to DoJ and the US government
