Wasn't that when Dario, et al were at the company. One way to view this is that OpenAI expelled the cultists and they went on to form their own organization that continued using the same tactics.

Certainly some of the Anthropic press around Fable seems to me to be just marketing but I also think there's a core of people there who really believe it. I also think like all good advertising/lies there's some truth to the claims even if they're exaggerating.
