> 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Blu ray discs can only (legally) be played in licensed devices, and some of the decryption keys can and have been revoked.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.

Do you have a citation for that? I don't believe it, partly because I can imagine the sort of class action it would engender.
There are reports of bricked players on the internet, and unbricking, but those mostly seem to have been caused by bad firmware updates.
The wikipedia page on AACS only mentions revocations affecting future content.

AFAICT, you're right.
A standalone offline player that can play Movie A today will be continue to be allowed to play Movie A forever.
Subsequently-purchased movies B, C, and/or D may or may not work (because of shenanigans like key revocations systems), but Movie A still plays fine even after these later titles have been introduced.
It's ugly, but it's not quite a brick.
The ugly part is shaped like this: A person buys a new movie and it doesn't work. They can't return the movie to the store because it's been opened, so now they're left with a disc they can't use and with less money than they had before. (Solutions include figuring out how to update the player's firmware if it's still supported, spending more money on a newer player, or becoming an Amish leatherworker and forgetting about all of this nonsense for the rest of their days.)
