“the military said no and therefore doesn't want anthropic used anywhere in their supply line”
It’s clearly a punitive measure and has nothing to do with national security.
If a supplier uses Anthropic to develop a product, how does that pose a risk to the DoD or national security? The DoD can specify that a third party system can’t rely on Anthropic for DoD use without designating the company a supply risk. It was very clear that the administration was punishing the company for saying “no”.
Anthropic took the position that our military’s decision making power should be subordinate to Anthropic’s constraints.
Any dependency on a company that thinks they have that moral authority and has the technical means to enforce it is absolutely a risk to the supply chain.
If you want to blame someone or something for this, we should start with Dario and “effective altruism”.
