I don't necessarily see Google as having a monopoly over the internet, but more as "The Gatekeeper" to the internet. Most people around the world go through Google if they're trying to reach somewhere (especially if they don't already have the target site bookmarked). The fact that they're the de-facto curators of content gives them enormous influence over people's perception of the internet.
The question is, do we want a largely unregulated private corporation to hold that much sway over entire populations?
There is no legitimate way to regulate tech, it's an optional thing that people can use or not use. Right now there are people who go out of their way to avoid using Google and they manage to keep their jobs and even get to work using less attractive open source map apps. The practice of regulating tech exists right now in China and unlike communism there's a real possibility of it spreading.
