There is a type of person like this, and I've seen them as the majority of upper management everywhere I've worked. But at Google, upper management is not like this at all. The CEO is the guy who co-invented PageRank. He holds weekly meetings where employees can get a beer and ask him questions. Google makes a lot of money, but it's not run like your average "big company". (When I worked at Bank of America, the yearly "town hall" meetings were invite-only. And if you were invited, the CEO stood outside the doors, spot checking employees to make sure they had Bank of America credit and debit cards. What the fuck!?)
Everyone is waiting for Google to become evil, but the infrastructure is just not in place for that.
None of these things preclude a shift though. It can be as simple as being a nice guy who pushes the team to focus on profitability a little more which causes them to compromise in ways they might not have done previously, or who defines evil a little differently.
As I think I said, I don't think anyone is suggesting that Google senior management are actively plotting how to enslave us all, but there does seem to be a pattern of things which suggest a shifting of priorities.
