"In the digital game case, Nintendo actually perfectly prevents online piracy here. Tickets cannot be forged, and Nintendo can verify that the device ID in the ticket matches the device ID for the client cert connecting (banning on a mismatch), as well as that the account ID for the ticket matches the Nintendo Account authorizing to log in. Users who pirate games definitionally cannot have well-signed tickets for their consoles, and thus cannot connect online without getting an immediate ban -- this is exactly how I would have implemented authorization for digital games, if I were them."
