Most readers are aware they were a research and advocacy organization that became (in the sense that public benefit tax-free nonprofit groups and charitable foundations normally have no possibility of granting anyone equity ownership nor exclusive rights to their production) a corporation by creating one; but some of the board members are implied by the parent comment to be from NGO-type backgrounds.
From the non-profit's perspective, it sounds pretty reasonable to self-police and ensure there aren't any rogue parts of the organization that are going off and working at odds with the overall non-profit's formal aims. It's always been weird that the Open-AI LLC seemed to be so commercially focused even when that might conflict with it's sole controller's interests; notably the LLC very explicitly warned investors that the NGO's mission took precedence over profit.
The CEO just works for the organization and the board is their boss.
You’re referencing a founder situation where the CEO is also a founder who also has equity and thus the board also reports to them.
This isn’t that. Altman didn’t own anything, it’s not his company, it’s a non-profit. He just works there. He got fired.
Many NGOs run limited liability companies and for-profit businesses as part of their operations, that’s in no way unique for OpenAI. Girl Scout cookies are an example.
