Wendy debates Fritz
Take a look at Wendy Seltzer's debate with Fritz Attaway (you have to follow another link from Wendy's blog post to read the text at the Wall Street Journal, and, in my browser, the text is squashed in a column at the very right hand edge of the page).
Both of them are quite eloquent. I think the most remarkable and important thing about the debate is Fritz Attaway's repeated statement to the effect that price discrimination (1) is good for customers, and (2) is the most important reason for DRM. (He observes that, without DRM, every retail media transaction would be a sale, or at least users would have the ability to treat it as a sale. And then he says that users who prefer to pay less for fewer rights would regret being denied the opportunity to disable themselves from making uses that they didn't pay for.)
I think it's useful to have an MPAA representative say that DRM is about price discrimination rather than "copyright". Almost every DRM proponent's argument about "new business models" seems to be an argument about price discrimination. Price discrimination is, I think, the fire that produces the smoke in the DRM wars.
