>The phone company isn't allowed to block you because you said something politically incorrect to my friends and tech companies should be no different.
AT&T does block their customer's email content without informing their paying customer. At this point I trust NSA more than these private companies. At least NSA has some government oversight and subject to FOIL request with these private companies it is basically the East India company all over again, wild wild west. They can do pretty much what they want. And like the Federal Reserve has their own private armies.
