The board will bring in an adult CEO who can balance the nonprofit charter with Microsoft and the commercial business, and who doesn't have a million side projects taking his or her focus away. Some employees will leave but the vast majority will stay for the usual reasons (i.e. inertia), the business will keep growing because ChatGPT is already a worldwide brand at this point and the vast majority of users don't give a hoot about any of this palace intrigue as long as the product works.
And the board will ultimately be vindicated for acting as fiduciaries for the nonprofit's mission and bylaws -- and not for the financial interests of Satya Nadella, Vinod Khosla, and the like.
