Congrats on packing a lot of trite, irrelevancies into a single post, you must have thought you were on the Huffington Post.
Was anything that I said untrue? And why are you - as a consumer who had no input into the contract that you signed - so quick to come to the defense of a multi-billion dollar corporation that will rape you for fees every chance it gets? If AT&T wanted to charge you 99 cents every time you turned on your iPhone, and they put it into the contract, would that be okay as well just because you signed the agreement? Does that make it "right"?
Just because it's in the contract doesn't mean it's fair, and just because you agreed to it doesn't make it right. If AT&T agrees to deliver 20 GB (or whatever) to my iPhone every month for a set fee, then what difference does it make to AT&T if that data goes to my iPhone or my MacBook Pro? It's still the same amount of data delivered over a cellular connection. Oh wait, now I know... it's different because AT&T can charge an extra fee for nothing more than a concept called "tethering". This is a pure profit center for AT&T and nothing more.
I won't cry over how much you people think AT&T is hurting over the egregious violations of their contracts and TOS by all of us unethical consumers who actually use our brains and take the time to peel back all the BS to see the truth. Try getting out of an AT&T contract when they unilaterally change the coverage in a particular area to be below what it was when you signed the agreement. See how far your ethics take you then.
