Google stock is organized into different classes with different voting rights and amounts of shares (a few years ago a new class came out without voting shares but got dividends first, if I recall correctly), and the founders have control as long as they want it. At the time, I thought this was dangerous since the current king might be good (ie the founders) but what if the next king who has control was someone who has wants to control people through tyrannical means using their entire life histories (ie google tracking on everything).
