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.
