This may be the tip of iceberg. In the 90's you only had an A and B Block wireless carrier. Consumers wanted more options which spawned the onslaught of regional carriers (Dobson, Suncomm, Cincinnati Bell Wireless, Iowa Wireless, etc.). Along with these giants (TW and Comcast) will be more consolidation in both cable, internet and wireless services.
While Wheeler (FCC Chairman) chases insignificant battles such as getting unlock codes for consumers, we will have less choices in the long haul which will eventually take us back to the 90's where the carriers will control pricing until we figure it our again. Over the years, less choices in the telecom arena has never been good for the consumer.
As JSF mentioned, net neutrality could create some major fireworks if the telecoms who own the fiber/wireless spectrum decide to make it difficult or impossible for companies like Netflix to be accessible. In addition, if you are a start up content company, good luck.
But at least all consumers will have an unlock code for their 2 year old outdated wireless device :)
