The government tracks you, your bank tracks you, insurance companies know everything about you. Google tracks your interests, and that's it, they don't even know your name because they don't care.
Google knows my IP address, my ISP, and all my web searches by ip address, which is more than the government. Why do you think the Gov asks Google for info? How naive are you?
Google Streetview knows who I am and where I live. Google won't share that info with you, or even my own data with me. You think this is OK?
