Not contradicting your point, but adding tangential interesting information.

Blu-Ray UHD discs can no longer be played on modern computers as Intel has removed the trusted execution environment needed to decrypt them. Blu-Ray UHD players do a handshake that verifies the use of Intel SGX.

One might have always been skeptical of these discs, especially as AMD had never implemented those TEE instructions.

But I believe the interesting takeaway is that even physical media is becoming something you can’t count on using without the continued permission/assistance of some outside party.

Without regulation I would expect that all new media will eventually require players to be always-online.

Why hasn’t the requisite software been updated to perform a non-SGX handshake? That seems like a yawning oversight. o_O

[jsheard]

The UHD DRM scheme requires some kind of secure enclave for key management, and SGX was the only suitable system for that on PCs. There is no non-SGX system they would certify.

That seems less than optimal.
