I think the carriers have taken exclusivity, as well as closed networks to an unacceptable extreme. It should never have taken Congress to start poking its head in consumer affairs. This is a very bad precedent, possibly leading to increased regulatory oversight, higher costs, and less innovation.
Markets should police themselves as much as possible. AT&T and Verizon are legalized monopolies who offer consumers little to no choice. It is always in the consumer's best interest to cause change (e.g., the twitter petition to try and lower upgrade prices). Federal intervention is not good. Why not nationalize wireless carriers? It's just money.
