This is going to happen on the Internet if Net Neutrality isn’t the norm. Pressure will be brought on companies to block things.

quick update: I should mention that Verizon backed down saying this is a mistake. Good for them. The larger point still stands, though: 1) they feel they can filter content, 2) they look to have the legal rights to do so, and 3) this is why common carrier status matters in this debate. They should provide the pipe and be freed of the responsibility over the content both from a control standpoint and a liability standpoint.
