LOL, look at the opposing organizations list:
Google, Yahoo, Facebook, Twitter, Reddit, AOL, LinkedIn, Ebay, Mozilla, etc.
This shit will never pass. I say fuck the artists/intellectual property owners. Allowing the ability to block DNS traffic, all for the sake of them is plain retarded. This is a dangerous path the government is going down. I wont even go there.
Furthermore, the artists should be spending more money to secure their property, not sway the opinion of politicians. Instead of blocking traffic (never ending battle), how about creating better more secure applications? Don't filter my internet because you can't manage the distribution of your own product.
