I agree with the other reply to you, but to address your point directly, it is probably true that a lot of the frontline workforce can't afford to leave, but the people in leadership positions and very high-level/well-respected ICs still have options (including, given given FB's pay and recent stock performance, the option of not necessarily needing to work). That's a small group but each departure would be noticed and they'd have plenty of leverage.
