It's the reality of the economics of TV. "TV" is "TV" regardless of whether you get it from streaming or cable. And that means the consumer cost is largely going to be the same. Back when everyone had cable, streaming was probably cheap for 2 reasons:

1. Subscriber acquisition practices to grow the streaming subscriber base kept cost down even if margins were low.
2. Streaming was the icing on the cake. So TV companies were happy to make content cheap for streaming when Cable was the main cash cow.
