Anthropic did not change the terms. Those were the terms the US Government signed. It was not secret, it was explicit identified and accepted as a term.

The analogy would be: “A customer agreed to a contract, and after running into a clause of the contract they no longer wanted to follow…canceled the contract unilaterally…which also violated the contract.”

And then declared the other side a supply chain risk, claiming it is a potential vector for a national adversary to break in and cause unwanted bad things to happen unrelated to this contract.

It seems like absurdly bad faith starting at breaking the contract (over "you have to follow the law", no less!) and then to retaliate after that with trying to destroy the company's reputation and ability to do business. The boot licking going on here justifying the government operating in bad faith is both disappointing and short sighted. I didn't think the leopards would eat MY face!
