> A Blu-ray disc, game cartridge, or printed book cannot be remotely erased, edited, or deactivated. It is a physical object you can own, resell, lend, archive, or play offline indefinitely.
Isn't this untrue with surprising frequency? Decoding devices phone home, come under new copyright laws, etc etc etc.
Blu ray discs can only (legally) be played in licensed devices, and some of the decryption keys can and have been revoked.
Key revocation only affects future disc releases.
AIUI every disc is mastered with the latest revocation list. When your device sees that it is revoked by any disc, it bricks itself.
