He's a good businessman, but that "deterioration" that you (and me and many many others) see is because he's not driven by the same morals and beliefs that Larry and Sergey had when they were running the company. The "old Google" everyone loved was the pre-Sundar Google.

I can't really blame Larry and Sergey for wanting to do something else, and leaving the company in the hands of someone that they know will maximize profits. But that doesn't change the fact that modern Google does a lot of scummy and downright evil stuff today that likely wouldn't have happened during the "old Google" days.
