That's the wild thing, they actually get less money that way. There are like 4 cases:
You have both a CR subscription and buy the Blurays (that's me).
You pirate the simulcasts and buy the Blurays.
You only stream.
You only pirate.
Cases 3 & 4 remain the same. Case 2 will not suddenly go to a subscription and case 1 already has a subscription. So cases 1 & 2 simply become cases 3 & 4. There is no extra money to be made, only less.
Technically there is a case 5, where you only buy the Blurays, but that seems very much an edge case or only theoretical.
