The author(s) of the cryptography.com article agree with you (though it seems likely that the encryption itself will not be the primary subject of attack):

Unfortunately, pirates will attack high-definition disc formats. Due to the large number of different player designs and usage scenarios, some attacks will succeed. As a result, long-term format security depends on having the ability to recover effectively.

Revocation can help contain some attacks by preventing future titles from playing on a pre-chosen set of players. For example, if studios learn that pirates have hacked a player with a specific serial number, revocation makes it possible to author future titles so they will never play on that player.
