Ezra sold his shares because institutions and Mutual funds will not by a stock that is 51% owned by an insider. He doesn't even own a third now, thus clearing the way for the big block buyers. He makes more now by opening the gates for really huge upside potential.
Those sales have to be brokered and approved for sale. You can't just dump 31,000,000 worth of a companies net worth at your whim. It has to be discussed with the board and whatnto first. There was a planned sale long before it happened. What I am getting at is that this was purely circumstance.
