In general, I would agree but it seems like the broadband provider space is a bit different. Those of us in larger metropolitan areas can freely switch between several providers but customers in more rural areas have very few providers to choose from (if any). Many of the companies that DO serve up broadband in these areas enjoy a kind of local-monopoly. They can do pretty much anything they want because there are no other competitors around. Consumers in these areas are pretty much screwed if their provider decides to cap.
I think the market will adjust though. If enough people get bad enough service, someone will come in and give a better service.
Assuming there aren't regulatory or other barriers to entry.
The US does seem pretty bad where these things are concerned though.
In the UK we have literally hundreds of broadband suppliers to choose from. Yes the majority go through BT, but the terms etc are decided by the broadband suppliers, so you have loads of plans to choose from - capped, uncapped, cheap, expensive, etc etc
