I wonder: Are you afraid Google is sitting at home drooling over the fact that you bought your shoes from JcPenny?
You’re not a name, you’re not a face, you’re a knode. a cookie. literally, a number in trillions of records.
Secondly, you sit on the web writing openly about privacy issues, while overtly displaying your information on those "Identity tracking" services you use, like Facebook, which If you spent the same amount of time you spend writing about how Google is out to get you, perhaps would understand that while you're browsing incognito, Google is having a frenzy with your gmail content, building a profile on you that you may never see.
At the end of the day, someone is always going to be collecting information on you, and your information will be again, one dot tied to your one number- among trillions of other records. There will always be internet ads.
To wrap this up, my point is that if you really don’t wan’t to be tracked, then cancel your credit card, pay everything in cash, disable your GPS, avoid connecting via Wi-Fi, forget doing ‘good deeds’ like filling out surveys, or giving your name and number to a blood drive. Oh and completely disconnect your router.
