The Internet is a grossly complicated system, and the ability to have nfljerseysupply.com resolve to your website is far from a given right. ISPs, web hosts, search engines, ICANN, governments, browser vendors, OS vendors, and more all have to cooperate for a domain to work. Each player has to cooperate to make your website reachable, therefore each player has the ability to make your website hard or impossible to reach.
It's scary if the US government has powerful legal tools to take down any website (see: China), but the US govt. has a track record of going after only a few criminals, not performing political censorship. So do all the players. Also, COICA, which would make this act easier, got gummed up in the Senate.
I don't know any details, but would you expect counterfeit websites to remain humming along while DHS raids warehouses involved with illegal manufacturing, importing or exporting of counterfeit goods?
The torrent search engine is a different beast, and by following legal precedent I'd expect the owner to be cleared of wrongdoing if and when it goes to trial. I also suspect the owner is being disingenuous, and was operating the site under a shell, making it difficult to find him and serve him warnings or legal papers.
I also interpret this as a sign that the media corporations are fucked. This is the best they can do with their global power, influence and money? Take out some counterfeiters and one lowly search engine?
Yes, we must be diligent against the government and corporations, but if this is all they have then it's nothing I'm going to get worked up over.
