Any case similar to this? What kind of boards you find to be more fitting for the case of OpenAI? It may not be Tesla but you’re probably drawing another reference from history, right?
It is hard to think of a case of a public charity that owns a controlling interest in a for-profit subsidiary and that is all they do. The Morman church owns a lot of businesses, but it is still the Morman Church.
Note that in the US, private foundations are not permitted to own a controlling interest in a for-profit company, so the example has to be a public charity. IKEA is controlled by a Dutch nonprofit foundation, but it has no obligation to the public except to give away a small portion of the profits.
