The problem is the branches of the government that Anthropic was doing business with found it infeasible to do this.
They had another problem. If one of their contractors used Claude to engineer solutions contrary to Anthropic’s “manifesto” would Claude poison pill the code?
Basically Anthropic wanted the angels halo and the devils horns and the govt said pick one.
That's not what the presidential announcement blacklisting Anthropic said. It said they're being punished for trying to require that the military follow their terms of service.
The media is usually flush with defending Anthropic. And yes - the supply chain risk label is too broad. But there is another side to the story and Anthropic isn’t an “innocent” as made out to be.
So he'll only accept systems developed by people who understand, as Sam Altman promised to, that the US military is not to be questioned.
