The only thing that surprises me is that I thought T-Mobile were the good guys. Apparently their stance on net neutrality was empty fan service.
Nothing digital has any semblance of privacy. If you want to take nudies with your significant other, buy a Polaroid camera. If you want to shake hands on a shady deal, do it in person. If it's not the company who develops your product screwing you, it's the people pwning them: just look at what happened to the bastion of privacy, Apple (the iCloud leak).
Stop trusting your digital devices, or, alternatively accept that you have no privacy (which is a completely valid choice).
