XKCD has a take on DRM that, while not up to the fantastic levels of insight I sometimes see from that comic, is definitely still right on target.
Sadly, it takes a really practical explanation like this rather than arguments about freedom. *sigh* And it's susceptible to the music industry saying "Oh, we'll fix all that!". It sounds like a set of engineering problems, not like a set of fundamentally broken ideology.
But, I suppose, given that the term 'Open Source' worked where the term 'Free Software' didn't, that's really the right kind of argument to be using. It's still kinda depressing though. It explains well why people don't really seem to care that our constitution seems to be mostly paper nowadays.
I did hear about that. It's very irritating.
