As you hint at, this is also a space where the FCC considers dial up and cell phone service (AFAIK) to be competitors when it comes to regulatory requirements. I got some copyright notices from a roommate's habits and Comcast was the only high speed ISP that was available at my house. Given that my work involves regular working from home, this was highly concerning.
At least they (Comcast) just send you an email now and don't inject their notices into the HTML of the websites you're visiting like they were doing a few years ago. It was basically a MITM attack, done by the ISP.
