I don't really think they're acting on a grudge against Anthropic here, I think it really is on Anthropic for describing the model's capabilities the way that they did.

IIRC Anthropic claimed to have been working with the government on securing things with Mythos, but then they seemed to have been blindsided by this.

My read is that the guys making the decision to restrict it were not the ones that Anthropic had been working with, and it's more about Anthropic getting caught between infighting within an incoherent government.
