The whole article reads as virtue signaling to me. Anthropic already has large defense contracts. Their models are already being used by the military. There's really no statement here.

The notion that it's bad to signal virtue is one of the crazier propaganda efforts I've seen over the last 20 years or so.

A company being asked to violate their virtues refuses, and then communicates that to reestablish their commitment to said virtues?

Tell me more about what they should do if a virtue signal in such a situation is a nothing statement.

Isn't it nice to have virtues to signal though? In saying that, you're saying you don't have any worth signaling over.
