We covered Cory Doctorow’s DRM talk here last week. It’s clear, well-reasoned, and covers a lot of ground. It’s also structured in such a way that both experts and neophytes can follow his analysis.

That industry people with stakes in DRM disagree with Cory is hardly surprising. What is surprising is the amazingly half-assed way in which Jupiter Research’s Michael Gartenberg did so. Without saying how Cory is wrong about DRM’s fundamental conceptual problems, he insists that nevertheless Cory IS wrong, and that he’ll be happy to explain why to paying customers (he also positions his pseudo-argument in a “what customers will put up with” way, which says an awful lot).

Er, right, Michael. Of course, given that way the music industry seems content to buy snake oil, maybe this is all the sales pitch they need.
