As reader libreuniverse pointed out in forwarding this, this is big, big news: large Internet service providers, on whom millions of people depend for their Internet service, are going to start acting as copyright police:
The short version: each ISP will maintain a database of "repeat offenders", with gradually escalating punishments, starting with warning letters, then moving to slowing down the subscriber's connection, and finally to cutting them off altogether.
This is going to hurt artists. It's going to drive unauthorized copying even further underground, onto the so-called "dark networks" where people use encryption and other forms of indirection to hide from the network provider (and therefore from everyone else except the intended recipient) what's being copied. Use of such techniques is already widespread, and now it will become common and normal. This means artists don't get credit for their popularity: it becomes more and more difficult for an artist to tell who likes them and where and why, because all of the sharing and the commenting and recommendation that goes along with it gets driven underground. The ISPs are essentially forcing fans to hide their love of their favorite artists.
