8. Patches and Updates. Blizzard may deploy or provide patches, updates and modifications to the Game that must be installed for the user to continue to play the Game. Blizzard may update the Game remotely, including, without limitation, the Game Client residing on the user's machine, without the knowledge or consent of the user, and you hereby grant to Blizzard your consent to deploy and apply such patches, updates and modifications.
That statement in itself covers them for delivering Warden updates and makes all such updates and accesses "authorised" for the purposes of the Act.
