The Pentagon's attempt to designate Anthropic a supply-chain risk followed the company's refusal to lift restrictions on AI use for autonomous weapons and domestic surveillance, a move widely seen as punitive. The judge's decision highlighted that the government's continued use of Anthropic's products and collaboration on AI oversight contradicted a genuine fear of sabotage.
