What about tiered plan users being forced into 4gb plans that cost 50% more than 5gb iphone plans (aka unlimited)?
Why should ANYONE on a well defined data plan (non-unlimited) have to pay additional cost to use that data that was paid for?
To those who have limited data and just want the ability to use it any way they like -- I totally feel your pain. I fully agree that it is really dumb of AT&T to cap the data and then charge you extra per device. It is non-sensical to anyone with a basic sense of logic. To me, why not let people use the data up and pay for more if they need it (i.e.: upgrade to 4GB if they need that much data or 6GB or 8GB).
But it is still does not escape the fact that they are the ones who erected the wireless towers and built up the network infrastructure and they can license it as they see fit. And we as consumers have the option to not license it at all. I think the more dumb decisions they make the more likely folks will change carriers or somebody else will come along that offers something better.
I think Cable companies have been sticking it to Americans for years even though they are subsidized with municipal permits to build out their network under public roads. Now better things are coming along and some of these Cable companies are scared out of their minds. First Dish Network and DirectTV offered a better alternative and now the potential for wireless WAN or other internet providers to replace the need for subscription television.
Cable companies are becoming a commodity for pure data. Eventually the wireless providers will as well But for now, if you sign an agreement it should be with the intent of keeping that agreement. Most folks would expect others to keep up their end of any bargain, why shouldn't these wireless carriers expect the same or enforce it otherwise?
