That's nice, but the problem is that "selling out" has strong pejorative connotations, while being completely vague. Does Bill Gates have a positive moral duty to all those "stakeholders" employed at MS, until the day he is carted onto his deathbed? Obviously not. What would that duty actually mean in concrete terms? I have no idea. In fact, at some point, trying to hold on and control the company is in the disinterest of stakeholders, as Gates' personal interest and abilities wane. TFA is pretty vague too. I do not sell anything particularly wrong with selling a company at 10% of what you could have gotten several years later. A "measly" 2-3 million dollars in a bank account buys you a lot of freedom. Diminishing marginal returns means that another 10 or 20 or even 30 million buys you less happiness than you might think.
