That's a big outpouring of public disgust with DRM. But it didn't win the war, because the publishers changed the key. Not only that: with HD DVD, this was adequate to break the DRM, but not with Blu-ray. Blu-ray has an additional level of DRM and so far there is no free software that can break it, which means that you must regard Blu-ray disks as something incompatible with your own freedom. They are an enemy with which no accommodation is possible, at least not with our present level of knowledge.
