Because they use personally identifying I for other than what you saw. In your comment does that mean you have a right to follow their personal life and invade it then sell it to others? No!

Your problem is you like being a commodity rather than just a consumer. You don’t mind your life being intruded on which could include cc numbers or bank account info. You want to lose your money like that that’s fine. Me personally, they can get out of my life and quit following what I want to do just to make a quick buck. Fuck that, me and my personal information is not for sale! And if anyone seems to think it is, I will stop them as that is my right.

Personally I think all tracking cookies should be banned on the internet worldwide! I am not a commodity.
