It's permanently available if you're willing to fly the black flag. I know a few people who hoard huge amounts of BD-rip movies on their multi-TB NAS at home. That way it's permanently available.

DRM is a scam on the law abiding consumer and the "Blu-ray Disc Association" is a cartel.

Honest question: do people still use PCs to watch BD movies? Have they ever? AFAIK the rare few people who still have a BD movie collections, use dedicated players or their consoles for that. Using a PC for that always seemed like masochism from a UX perspective so it was never popular.

To play the devil's advocate, I think it was too expensive for Intel to invest in patching the SGX IP block vulnerabilities, porting it to smaller nodes, and wasting valuable silicone die, just so the last 5 remaining people on the planet who still use a PC to watch BD movies can now do it from a brand new PC instead of using their existing ones.

So, ultimately this problem backtracks to the use of DRM and why that's bad, not on Intel who can't financially justify supporting such old & niche DRM IP moving forward.
