the real problem
Granted I am not a wonk on this topic and will probably get downvoted to heck but it doesn't seem like the solution is to tell ISP how to manage their traffic. The solution IMHO is to treat all ISPs as common carriers (especially cable) and eliminate this early 20th century commanding heights BS of cable companies having regional monopolies. Don't tend to sprout right winger ideals but regulation first and foremost should exist to make sure their is always a healthy and fair market because market forces can often do what regulations can't. People will naturally tend to choose the company that doesn't throttle their use cases if they have say a dozen different choices for ISP.
