Well, it can, and that's a huge problem if it happens. What Comcast is doing doesn't trigger this problem (the page that Comcast refers people to isn't marketing anything that Comcast folks don't already get for free as part of their subscription). Rogers, on the other hand, experimented with this kind of system to sell people more bandwidth. That's a problem.
The ISP isn't paid to get in the way of desired communication. However, if you're infected, the ISP ought to shut you off. Comcast has figured out a way to avoid that shut off, and customers should find that as less objectionable. As long as it is not abused, like you point out.
