Earlier quoted context omitted.
Why should the law protect loss leader strategies? My local supermarket does not get some special legal protection for its loss leader strategy with milk and eggs. What makes cell phone companies worthy of this special protection of their business, which puts independent cell phone stores at a substantial disadvantage?
Aren't airlines providing cheap tickets at a discount rate but with extra restrictions (no baggage, etc.)? Or discounted tickets that cannot be turned back, even when you are sick? I mean, if you don't like that, by an unsubsidized phone. I don't see the special treatment of the cell phone companies.
The special treatment is the DMCA, which forbids you from unlocking your phone regardless of the contract. This gives the cell companies an advantage by protecting a loss leader strategy: it is less risky for them to sell you a phone at a large discount which is locked, because it is illegal for you to unlock it whether or not you are under contract. It would be as if an airline sold you a discount ticket, and the law forbade you from having another company carry your luggage.
