If you read Sam Altman's actual comment, it's really clear that he wasn't committing to anything with OpenAI. He was barely committing to anything in his own personal opinion.

"I don’t personally think the Pentagon should be threatening DPA against these companies. But I also think that companies that choose to work with the Pentagon, as long as it is going to comply with legal protections and the few red lines that the field, we have, I think we share with Anthropic and that other companies also independently agree with, I think it is important to do that. For all the differences I have with Anthropic, I mostly trust them as a company, and I think they really do care about safety, and I’ve been happy that they’ve been supporting our warfighters."
