I’ve been saying it all along.
I watched a clip on YouTube pirated from a DVD I own. The uploader added music, turned it into something new and wonderful. And that’s a breach of copyright on two fronts (derivative work and stealing music).
I’ve been saying it since Napster: if content (music, movies, books) are going to be easy to share –and they are– just make it super easy to BUY it and people like me will.
