The thing here is that the structure of these companies and the operating agreement for the for-profit LLC all effectively mean that everyone is warned going in that the for-profit is beholden to the mission of the non-profit and that there might be zero return on investment and that there may never be profit at all. The board answers to the charter, and are legally obligated to act in the interest of the mission outlined in the charter.
