Suppose that we open a non-profit to cure cancer, you and a bunch of others give me billions, I cure cancer, great. Then plot twist, I turn the non-profit for profit, I avoid releasing the cancer cure I promised and instead I charge you for cure. If a non-profit promised to cure cancer to help citizens, I would want that at the very-least they remain non-profit.
