Something I don't fully understand, from [1], Altman was an employee of the for-profit entity. So to fire him, wouldn't the non-profit board be acting in it's capacity as a director of the for-profit entity (and thus have a fiduciary duty to all shareholders of the for-profit entity)? Non-profit governance is traditionally lax, but would the other shareholders have a case against the members of the non-profit board for acting recklessly w/ respect to shareholder interests in their capacity as directors of the for-profit?
This corporate structure is so convoluted that it's difficult to figure out what the actual powers/obligations of the individual agents involved are.
