immediately abused for DRM? If you look (somewhat) closely, it's hard to avoid the impression that this stuff was designed and built around DRM use cases.

The "Protected A/V Path" could be a neat feature for high security computers (consider the GPU driver, a horrible, buggy, complex piece of software, being unable to grab pixels of a security-labelled window) - but that's not what this was built for. SGX, the same.

Non-DRM use cases seem to be an afterthought, if possible at all (typically not).
