"In other news, Comcast announced that the NBC Universal websites will throttle speeds for non-Comcast customers. AOL is belived to follow with non-Verizon customers. Fox and Disney are believed to be in discussion for similar deals with AT&T and Charter."
Another issue that undermines the United States political system us the lack of proportional representation in legislative bodies.
A party could get second place with 40% of votes in each circumscription but get no seats, as long as they don't win at any. That's why unsatisfied Republican and Democrat politicians won't leave to organize a third party with a purer ideology (like libertarian or anticorporation).
Here in Uruguay, a party with roughly 1% of votes gets one of the 99 seats, no matter where did they get the voted. And we also have proportional representation of departments, with a little overrepresentation of less populated drpartments.
"A cap is usually better understood as a threshold after which the user is subject to a different set of conditions for access, such as movement to a higher priced tier, different product or different speeds."
If after reacing the 200 GB or so the company would provide a slower connection (say 1 Mbit/s), that would be a flexible data service. But cutting access to 0 Mbit/s is a data service cap.
"A current TWC subscriber would be moving from a TWC monopoly in service to a Comcast monopoly in service."
Well, yes. But residential subscribers aren't the only customers. Internet companies are also customers.
Suppose that Facebook has a project to install a super connection between their servers and Internet providers. If there's seven internet providers with each under 20% of the market, the project is tricky to do.
But if Time Warner Comcast had 40% of the market, Facebook can choose to connect to them only and ignore the rest of the internet providers. This is a huge advantage for TWC, and kills their rivals. In addition, TWC could set a very high price for the deal, whereas in a less concentrated market each provider has much less bargaining power.
