I completely disagree with this statement. As I stated in my post, data usage has grown and continues to grow exponentially. At what point would you say that AT&T shouldn't be forced to keep up? If all users used 5Gb/month, 25Gb/month, 1Tb/month? At some point we shouldn't expect AT&T to have to maintain a network where users are constantly upgrading their usage habits. AT&T couldn't have predicted how widespread data usage would have become back in 2007/08 when they first offered these services.
And it does harm all of us. A user who has jailbroken his phone and is using mywi to run internet throughout his home is slowing down the network. And this is the individual's fault for breaking the TOS, not AT&Ts. This is the same person though that will yell at AT&T (and threaten to sue) for changing the TOS to him. He feels that AT&T should abide by the rules even though he doesn't.
