I smell a turnover strategy here: 1) Buy talent in the form of companies while they are still cheap because of both the startup glut and the booming stock market (and thus yahoo stock price). 2) When the inevitable downturn/crash happens, seize the moment to clean house. Many other companies will doing the same so it won't be particularly newsworthy. 3) The alternatives for the remaining employees will be much more grim at this point, so they'll get to keep most of them for a good number of years in order to build something revolutionary.
