It's true, they're not like Microsoft in their method. But every good thing they do makes us more dependant on them. Even if the founders are without spot (hard to believe given the "if you have something to hide" comment), they wont live forever. What will we do when all competition has died off thanks to Googles goodness and they decide that "evil" means "things that don't make us more profits"?
I don't hate google, I use them for things. But I really hate the wreckless abandon with which people embrace them. The market can't "correct" them when they do wrong because they have another source for their income.
