The commpage had a different message that came from the DSMOS kernel extension which implemented the encryption stuff.

    Your karma check for today:
    There once was was a user that whined
    his existing OS was so blind,
    he'd do better to pirate
    an OS that ran great
    but found his hardware declined.
    Please don't steal Mac OS!
    Really, that's way uncool.

The ARM builds don't have DSMOS.kext, so I imagine the commpage message is gone.
