Amazon is bigger than Google. And yet, its leadership is only Bezos ever since it started. Sure, it might have a CFO or CLO, but when it comes to calling ultimate shots, there is no doubt regarding who is in charge. That's not the case at Google where it seemed no one wanted to take charge and put his/her stamp on company's execution.
So what is holding Sundar back now that the founders have checked out? FWIW, Nadella doesn't have majority voting rights in MSFT, but you can see his clear stamp on the company's execution (de-emphasizing Windows, for instance).
