Unless your ISP is a content owner, which several are now. Comcast/Xfinity is NBC for example. Plus Comcast makes a lot of profit on cable TV, so they have reason to ger people to stop. That being said, I dont know anyone who was simply downloading for personal use who got their service canceled. But it is a major risk in the IS since most ISPs have near monopolies at least over broadband speeds, so the majority have no other options.
