This is very interesting. You wouldn't normally hire an investigator to dig into a corporate shitshow. Firing of Sam Altman was a huge mess, but if there was a serious reason to do that (like, frauding the board), and that reason would be backed by investigation report, it'll suddenly make board actions much more justifiable. And it'll put Microsoft into a tough spot, because they hired Altman back without any considerations whatsoever...
If there is misconduct from Sam - he will get fired. If he succeeds - MS will benefit from whatever success means.
On the other hand, other competitors won't be able to porch Sam at this point. This is something many do not get. Whatever happens in the next few weeks to month, it won't hurt MS and won't benefit others, while on the outside we play the corporate compliance game.
OpenAI definitely needs professional structures. And MS will help them achieve that.
