Here's a wild video of Michael Moore at a Q&A session, being asked if he minds people on file-sharing networks passing around rips of his movies. His answer, in a nutshell: "Share away!"
I don't agree with copyright laws and I don't have a problem with people downloading the movie and sharing it…as long as they're not trying to make a profit off my labor…
I make these movies and books and TV shows because I want things to change, and so the more people who get to see them, the better.
(Thanks, Kolano!)
