Google founders don't own Google any more, at least they only own around 16% of it. The vast majority (80%+) of the rest of the stock is held by institutional investors who want one of two things: (1) capital growth (that is the share price to go up) and (2) dividends (that is for them to be given money for owning the stock). There is no room for Google as some non-business utopia, it's a corporation with a responsibility to shareholders. So long as Larry and Sergey keep delivering a return they'll be allowed to keep doing what they want but the minute they're not seen as doing that they'll be replaced.
