The Internet is simply an effective tool for connecting people. Whether the network becomes a force for good or evil is up to its users. It's only because millions of people have mobilized in defense of our rights to connect and communicate that the Internet pendulum occasionally swings toward doing good.
Google works very differently from other companies that have been dubbed "gatekeepers" and that are regulated accordingly. We are not a ferry, a railroad, a telecommunications network, or an electricity grid with only one line serving you and no competitors allowed. No one is stuck using Google. People have choices, and they exercise them all the time. We know that if we cease to be useful, our users will leave. The barriers to entry are negligible, because competition is just one click away.
