Comcast cancel accounts for too much usage

Regardless of what the position is in the UK, is what is happening in the USA a crystal ball into the future as far as usage by ISP customers goes?

Comcast have summarily cancelled some of their users' accounts for excessive broadband usage, with an ominous PR statement:

"Comcast has a responsibility to provide these customers with a superior experience and to address any excessive usage issues that may impact that experience," Comcast spokeswoman Shawn Feddeman said in a statement. "The few customers who are notified of excessive use typically consume exponentially more bandwidth than the average user."
