Read this NY Times story about how the U.S. is "purusing a middleman in web piracy." Sounds ominous, but it's not.
He's a 24-year old who ran a search engine that found torrent files. His mum, who was interviewed for the story, says whatever money he made is gone. "He would take his mates to the cinema and pay for them." This is what the US legal system has been reduced to. Humiliating.
Meanwhile, to see just how cowardly this is, if you go to Google, a multi-billion-dollar company whose execs serve on blue-ribbon White House commissions, you can get exactly the same information.
Here's an example search which returns torrents for an awful Hollywood movie that has grossed almost $1.5 billion so far.
So Google, too, is a "middleman in web piracy." This isn't new. Google has always returned these results, and they're right to. That's what search engines do.
