Maybe Microsoft holds some sway? Sam made a snide tweet at them a few days ago. Running the whole Dev Day demo on Mac's might also be taken as some kind of statement.
Haha yeah they are kicking out the CEO of their most profitable venture because he uses a mac.
The Mac thing would have nothing to do with it. Microsoft's own employees use Macs during demos
Sam strikes me as the type of founder who would never sell out or accept an acquisition. With $10 billion already invested, what's to stop Microsoft from trying to acquire them?
DevDiv uses Macs all over the place.
OpenAI is a Foundation. IANAL, but I don't think it can be bought by a company.
Microsoft has no board seat
Even so, I'm sure Satya could get his opinion heard by many of its members if he wanted to.
