Cory Doctorow appears in an interesting video where he discusses the politics of copyright and how our current policies just don't make any sense. He repeatedly applies those policies to other areas where everyone can see how ridiculous they are. Somehow, though, as soon as we start talking about “media” people think it all makes sense.
The video is about 17 minutes long but well worth your time. Watching it made me angry at how stupidly we're behaving and that no one can see that the purpose of copyright as currently applied is the preservation of the business models of a few large conglomerates. It's shameful, really.
