I completely agree. AT&T has absolutely no right to spy on it's paying customers, especially if there's no existing proof that they've done anything wrong. What's next, WalMart is going to have spys follow me around to make sure I don't resell the chocolate milk I buy, and use the resell money for illegal drugs? Is McDonald's going to make sure I don't get an eating disorder by puking up my food?
What's really sad is everyone's been quite upset about the fact that the NSA has been spying on people. However, when their own ISP's do the same thing, no one will care.
If there are any AT&T customers out there, I strongly recommend that you cancel your contract with them, and switch to someone who doesn't treat you like an automatic criminal (if there's anyone else left). If AT&T asks you why you are cancelling, make sure answer tell them in the strongest language possible.
