I'm disappointed and concerned by this. The Wikimedia Foundation has long had a policy of ensuring that their projects use free and DRM-unencumbered formats to make their content available to the broadest possible audience, whereas W3C is now supporting the notion that DRM-encumbered media (in other words, media that is, by design, made permanently inaccessible outside of some proprietary and easily-monopolized HW/SW combination) can somehow be part of the "open" Web.
