‘Open Source DRM’ vs. Free Software: RMS, Lessig in Register
The Register is running a nice, long article on Free Software and DRM. It has Richard Stallman’s view on DRM in general, as well as Lawrence Lessig’s sort-of-endorsement of Sun’s "open DRM" in particular.
While the matter under discussion is hardly breaking news, the article sums the problem up nicely.
Those who prefer their information only moderately pre-chewed might want to read Ciaran O’Riordan’s summary of DRM and the GPLv3. (He has another one of those on patents right here.)
