Why is the $1 added to the subscription cost? They don't redo the subs every month. It's developing subs once and then enjoy the benefits forever. It should be a cost that's amortized over something.
Well, it's not completely crazy. They don't redo the subs for an old show every month. But they do create new subs for new shows every month. They have constant, ongoing costs of subtitle development, and if they permanently increase those costs, they will be spending additional money (compared to the alternative) every month forever.
