If your goal is to have people doing creative, innovative work, then I would strongly disagree that there is any advantage whatsoever to be derived from making people feel "locked in." In practice, I have only seen this achieve the opposite effect -- disengaged people hanging around longer than they should and poisoning the atmosphere for passion-driven folks around them.
Joe's post made it quite clear that Facebook's management strategy is to provide freedom and autonomy, not handcuffs. This is one of the key reasons people love working there. The only thing Facebook is "squandering" is the opportunity to be experienced as a corporate financial prison.
The idea that any of this would be driven by Zuck's personal desire for liquidity is way off the mark.
