If it's truly about a power play then this will be undone pretty quick, along with the jobs of the people who made it happen.
Microsoft has put a vast fortune into this operation and if Satya doesn't like this then it will be changed back real fast, Ilya fired and the entire board resign. That's my prediction.
Ilya is a co-founder of OpenAI, the Chief Scientist, and one of the best known AI researchers in the field. He has also been touring with Sam Altman at public events, and getting highlights such as this one recently:
OpenAI is where it is because its models are much, much better than the alternatives and pretty much always have been since their inception, not because of anything on the business side. The second alternative or open source models reach parity, they will start shedding customers. Their advantage is entirely due to their R&D, not anything on the business side.
