That's beyond the authority of the DOD. What the DOD can do is say that Anthropic's products cannot be used on defense contracts. So Boeing programmers can't use Claude on a defense contract, but they can still use it on a civilian contract. Similarly, AWS or Azure can still be used by Anthropic, but they cannot use Anthropic in their defense work.
