I think it's definitely true that you should never count on a company to do principled things forever. But that doesn't mean that nothing is real or good.

Like Google's support for the open web: They very sincerely did support it, they did a lot of good things for it. And then later, they decided that they didn't care as much. It was wrong to put your faith in them forever, but also wrong to treat that earlier sincerity as lies.

In this case, Anthropic was doing a good thing, and they got punished for it, and if you agree with their stand, you should take their side.
