Yes, but both of those are not Microsoft's doing but the OpenAI board's doing. You don't just get to name someone to a board without the board to agree to it and normally this happens as a condition of for instance an investment or partnership.
Nadella was rightly furious about this, the tail wagged the dog there. And this isn't over yet: you can expect a lot of change on the OpenAI side.
Yes, that probably was a mistake, it should have come with more protections. But I haven't seen any documents on the governance other than what is in the media now and there is a fair chance that MS did have various protections but that the board simply ignored those.
