I feel like in this thread no one is understanding what supply chain risk designation is. The government can just not use Anthropic, and that's exactly what they're doing, and they are not using it so much that they don't want Anthropic anywhere in their chain of supply. It's not necessarily punitive, the government is just covering their tracks so that if somewhere in their supply chain Anthropic exists, they want to remove them. They are complying with Anthropic's demands to not be used in war and the DoD says, okay, we won't use you anywhere and also enforce that we won't use you, just like you wanted.

That's exactly what they're doing. It turns out the DoD is a really big bureaucracy and has process to make sure they thoroughly exclude a vendor and transitive dependencies on that same vendor.
