The desire to support the unreasonable demands of the film industry here has led to the perversion of the x86 architecture to add all sorts of peculiar DRM functionalities, and has precluded firmware components from being made open source; as I have previously written about here [1], which links to forum posts by an AMD engineer:
I'm sure I don't have to explain to you that the essense of DRM requirements in the OEM PC market is that the owner must NOT have full control of the machine if that includes being able to tamper with or disable any of the DRM mechanisms.
At the end of the day if Intel was going to support this kind of thing AMD also was pretty much going to be required to make such a deal with the devil, or have a product that can't compete with Intel. If Intel is losing interest in supporting video DRM, perhaps due to shifts away from physical media, it's likely to have a positive effect on both Intel's platform as well as other platforms which feel the need to support the same DRM platforms.
