While a lot of us (including me) never heard of it, it's apparently never been hidden. Turns out that most of my friends laughed at me when I brought it up (sniff). There are a handful of (American) Senators who've been ranting about this for years.
However, there are two versions of the story. The real version is that, as telecommunications companies upgrade infrastructure, they want to sell the extra bandwidth to the highest bidder, basically. The best analogy I can find is how couriers have an "expedited" service. There's really nothing wrong with that, unless someone declares the Internet an infrastructure thing that needs to be maintained and run by the government. (Aieeee!)
But then there's the conspiracy theory, that (starting in Canada in two years) the ISPs are going to turn all Internet access into a "managed interface" like AOL used to have--preselected destinations and content, where it'd be hard or impossible to get outside the interface. I'm not sure how much stock I put in that version of the story, considering that AOL itself dropped that interface because none of their customers liked it. I think Prodigy almost went bankrupt before that, because nobody liked the isolation.
There a possible middle ground of "pay as you go," except for Official Sites, but...maybe people who pay for bandwidth would find that acceptable, but most people I know would cancel service that very day.
