Yeah, that's fair. It was a completely stupid requirement from the association, even when SGX was available in consumer chips. And it was made even stupider by the fact that they seem to just be content to leave UHD blu-rays in limbo instead of coming up with an alternative that allows them to be played on newer hardware.
Hell, the people working on disc ripping software have been working harder to find ways to play the discs on modern hardware than the Blu-ray Disc Association has. The only option is to use unauthorized software to play the discs on modern AMD and Intel boxes, and that's the solution I guess?
