I think this misses the main reason. I mean ads have been a thing for a while now. What's new is:

* Brockman donates $25m to a pro Trump super PAC

* Altman is in talks with talks with the Pentagon since Wednesday

* Now it's announced Anthropic is dropped by the military, designated a supply chain risk, and OpenAI takes over its military contract, after Anthropic objected to surveilling US citizens and allowing autonomous kill bots.

The thing stinks rather.
