The basic point is that the current regulated universe has about 4,000 to 5,000 entities. With Bill C-11, the range of entities that would come under CRTC jurisdiction may get up to several million. Indeed, there are no limitations, as far as I can see, on the range of sources because it's just an IP address, of which there are billions, so take your pick.
The basic premise of Bill C-11, and the broadcasting telecom review that preceded it, is an almost infinite faith in the wisdom, capacity and talent of government to make complex and difficult decisions. A government is good at making some decisions sometimes, but with the range of authority being handed over to these people, who are only human, after all, and very much bound by law and regulation to make decisions in a slow and deliberate way, it won't work.
