In theory, this is why there should be competition in industry, because it removes the capability of a single large actor to be able to control the government's access to things.

Oddly, though, it seems like that should solve this problem as well. I'm not sure why the Department of Defense insists on Anthropic's models in particular; one would think one of the other players, at the very least least xAI, would be willing to step in and provide the capability Anthropic doesn't want to provide.
