"After acknowledging that, however, he goes on to define an open web as a marketplace, something that is “universal in that it can contain anything”, rather than being universal in that its content can be read by anyone." That's a very naïve view and one that I wouldn't expect from TBL. The open web, as a marketplace, is already universal in that it can contain anything. Every single one of the things that DRM is meant to protect can already exist on the open web. The problem is that the publishers are too stubborn to allow content without DRM. That's either a legal problem or bureaucratic problem, but it is certainly not a technical problem. The W3C should only be standardizing technical solutions to technical problems, not technical solutions to social or legal problems.
