Google's power over the web today, already, is not healthy. There are a lot of people within Google who care deeply about the free and open web, and a lot of people who don't, or who define "free" or "open" in ways that involving trusting a for-profit corporation more than anybody wise ever should. Many people get upset when they see Google being attacked, because the part of Google they depend on is a part that really supports the free and open web, or because they themselves don't value the freeness and openness as much as they should.
Google delivers a lot of value right now, and without people pushing back, hard, that value will enable them to get away with anything.
Anybody who has been around long enough ought to understand that power you grant to someone you trust inevitably ends up in the hands of someone you don't. Political parties switch back and forth, CEOs and corporate priorities come and go. Sometimes it's best to accept an option that is second-best today in order to avoid giving too much power to the organization providing the first-best for them to misuse tomorrow.
