I think it's interesting how much Intel threw a wrench in the works by killing SGX on the consumer chips. Official UHD blu-ray playback software was required to use SGX, so now no modern consumer machine can officially playback UHD blu-rays. I think all the payback software eventually deprecated UHD blu-ray support altogether due to this.
And any developments like the one detailed here also ended up being moot (at least in the consumer space).
Although, I'm not likely to cry over lost DRM schemes anyway, especially since games makers can't manage to preserve their games and have for years been relying on piracy for preservation.

Don't you mean the Blu-ray Disk Association threw a wrench in the works by requiring a poorly designed, tested and implemented technology? It wasn't ever supported on AMD CPUs AFAIK, and viable attacks started 2017/18, just a bit more than a year into UHD BD availability…

I think the biggest wrench in the works was just that UHD BD was effectively a dud due to streaming https://www.hdtvtest.co.uk/be/uploads/Screenshot_from_2025_0.... I think I hear/see more about it from pirating communities and notes about the death of SGX than actual players and disc in stores or friend's houses.

Isn't this the same story as Intel TSX? I remember looking at it when announced thinking it was amazing. As it turns out, it probably never worked anyways because the implementation was too buggy. It was later removed from CPUs that had already been sold via a microcode update ostensibly due to security. Then it was removed from most of Intel's product line entirely.
