Capitalism is all about free enterprise and the people managing a Nation's resources according to ability, as opposed to the politicians owning every asset and decision, including your way of life.
Socialism ignores and suppresses individualism, freedom, and other natural human inclinations, favoring the apt and the connected over the handicapped, as in slavery. They are on a "noble" cause to build a "perfect" society in their own image.

True capitalism is based on fair competition with low or no barriers to entry, which is in most cases more effective than regulation, yet some regulation is needed to preserve fairness. Pure lawless capitalism ends in anarchy.
You can't have true capitalism in the absence of a strong and fair justice system. Laws, not Kings nor Dictators, even if benevolent, as every one of them has to be so, to some degree, to an important sector of society, or they would be short lived.
The overregulation or chartering of an enterprise economy plus a strong authoritarian, socialist regime has a strong name to it -fascism.
Most Americans have never lived under oppression, and may not recognize it from the onset. I have, so please excuse my lengthy diatribe.
Wireless carriers are concessionaires. They paid billions of dollars for the exclusive rights to portions of the rf spectrum. They will fight commoditization of their service and will milk this cow to the last drop.
Hopefully, Apple pulling AT&T out of encroachment will lift the others and result in the accelerated modernization of the US wireless infrastructure.
(All flaming coming my way is understandable, if you have an opposite point of view. I respect you and will not try to convince anybody. Peace)
