Oh please, stop being paranoid and uninformed.
According to my calendar it's 2015. There's a sector of the industry known as "Big Data" if you had one sliver of knowledge about what Big Data does, they make Google look like clueless first grade children. But no one is going to be any more aware of it than you presently, unless they care enough to do the work and research it. It's neither advertised, nor as easy to find as the next new movie release.
If you wish to be relevant and knowledgeable about what's really going on, learn about the companies who's only job is to gather your data. Once you have a grip on that suddenly you'll laugh at your former image of Google.
Yes they track your buying habits and other non threatening preferences like airlines and such. They can then sell ads, you get a massive advantage of All the Free Google services. Services that so many people use frequently, they have forgotten just how much they rely on Google.
It's Google that's changed and continues to change the world. But like anything else that one gets for free suddenly they don't value it like if they had to pay $90,000, like so many do for a new German Luxury Car.
Google is loved by many and only hated by the paranoid, under informed , victim types.
