stop buying their products, stop renting, stop going to the theaters, stop buying music, stop listening to the radio (internet included via I-Tunes, Napster, etc.), watching TV, and RIAA and MPAA will go away, they'll learn that they can't just expect everyone to buy crappy music/movies for $20 or more, and that downloading off of the internet is a very small ripple in a very large pond. the reason why they dont' make money is simply, they think we'll pay whatever for their product...
Ok, now that you've dismissed that, get over yourselves. Don't like it, stop buying, downloading, copying, burning, etc... That is the only way RIAA and MPAA will wise up and stop demanding, and perhaps lower prices and sell more product. And certainly, that is what it will take before they figure out digital transmission is good, even if they don't sell every copy that gets transferred.
