ISPs send email citing that X external organization representing Y media company says that you have been sharing Z content, then the ISP shuts off or redirects all web traffic from your location except that which is allowed to go to a webpage they specify in the email where you must acknowledge that you got their communication and will cease and desist. It is pretty Orwellian.
We all need to switch to mesh wifi internetworking as soon as possible. With some work, it could become a better solution than our current net, and there would be no monthly cost to an ISP, and no MPAA, RIAA, or government interference. Granted, there is value in rule of law and protection of adequate compensation for created works. But when Big Brother comes down on you and your neighbors, is that ok? These guys would have cuffed you for the cassette mixtape you made for your girlfriend in the 10th grade if they would have known about it. The longer you let the ISPs or the government rule the net, the less of a chance you will have to ever get it back.
