It's really none of Microsoft's business, they invested knowing they wouldn't have a seat on the board.
I typically interpret "pissing match" to be a power struggle based off of competition unrelated to the core business. It sounds like the "disagreement" you are responding to asserts the exact opposite of that. Are you saying that there can be no credibility to the assertion that there were substantive differences about the non-profit nature of OpenAI?
You can dress it up however you'd like, quite frankly I enjoy the show regardless of being right or wrong. The point is they made it a show. If I were say a senator I might be having second thoughts of putting "AGI" (it really is a useful boogeyman!) in their hands.
