It’s safe to say the general consensus is against AT&T charging for FaceTime over cellular in iOS 6. The carrier is expected to introduce some sort of fee for Apple’s video calling service this fall, and AT&T has been trying its best to keep the issue quiet for as long as it can. While you would still be able to use FaceTime over a WiFi connection, carriers like AT&T obviously doesn’t want a bunch of video calls hogging everyone’s bandwidth.
Minnesota Senator Al Franken has been very vocal in the tech scene for years. He famously emailed Steve Jobs about the iPhone tracking debacle back in 2011, and he has continued to stand up for consumer privacy rights with the carriers and companies like Carrier IQ.
Franken recently spoke out on AT&T potentially charging its subscribers for FaceTime over cellular, noting that it would be flat-out “wrong.”
