Here is something I just posted on AT&Ts FaceBook page:
I own a phone that I purchased independently of ATT but use on their service. I pay them a significant amount of money each month for the service they provide on MY phone (and with this I have no issue). Android offers applications in a market that ATT will not allow me access to because they think it is inappropriate for me to use on MY phone. I pay for unlimited data (capped at 5 GB a month) and I should be able to use said data in whatever capacity I see fit as I have paid for it. What difference does it make if I use the data kb per session or mb per session?
The issue that has arisen now is with the Atrix. For all intents and purposes, the phone is a computer. It is the driving force behind the dock. The dock, to the best of my knowledge, contains no computing functions. It is a screen and a keyboard. If I did not have the ability to see web pages or my email on the phone (i.e. it was a modem/router) and I had to connect it to the dock to see the data I again would have no issue. This however is not the case here. If I connected my Motorola Razr to my computer and used it to view apple.com or weather.gov then yes, charge a tethering fee...I am using the service outside of the scope of which it was designed. This phone, and many others, were designed to make calls and view data...and they make money on this fact by saying other networks do not allow you to do it. It should not matter on what format I view the data.
ATT also fills their phones with "bloatware" which the consumer is unable to remove by normal means. This is the case if you buy a supplemented phone from ATT or if you buy the phone outright from the manufacturer. So with this, in conjunction with their blocking of applications and prevention of "side loading" applications, they are dictating what the owner can and can not do with a phone what is the his/hers.
Imagine if you went to your auto dealer and purchased a new car and the dealer said "O.K. you may go to [big box store] and purchase after market radio a or c but not radio b. (even though b works fine in your car and every other car on the market) And we know your car can do 110 mph but do not go over 55 (even though the speed limit in your area is 65) or we are going to add an additional fee to your next months payment. Oh and one last thing Mr. Customer, even though your car is designed to carry three passengers we are only going to allow you to carry two. If you decide to carry three we are going to charge you an additional fee on next months payment." Are you going to purchase from this store or are you going to go down the road to the other dealership? How long do you think auto dealer number one would stay in business if the word got out that this was their business practice?
