We own all of your data.
Google has a monopoly on search because they can better target what you want to see because they have this little thing called Google analytics running on almost every major website.
Websites want to be on the top of the searches so that people can find them. The first thing they do is embed Google analytics. Without it, your page rank drops dramatically. Right El Reg? (Notice how no one at El Reg ever reports on this little known fact? ) This is why no other search engine or technology can touch Google. And also because their algo for page searches is proprietary, we have no way of knowing.
So every time you search... they know. Even if you use a different search engine to find the page because the target page reports back to them.
So the Chocolate Factory can print money. They can censor things or promote things at will. In short, they can influence your purchasing decisions without you realizing it.
Google doesn't want you to know so that they best thing that they can do is to attempt to influence politicians who don't understand and don't care as long as they keep getting re-elected and rich while in office. (At least here in the US)
Google doesn't want the US Government to upset the apple cart, so the only thing that they can do quietly is lobby the government.
If you don't believe me, run NoScript and see what sites have Google Analytics.
Posted Anon for the obvious reason. Google doesn't want the truth to get out.
They are more powerful than any single government. They know more about you than the CIA, NSA, MI-5, MI-6, FSB, etc ... combined.
