Yeah, I can easily see something like 2 separate at $20/month vs 1 super at $35/month (make-believe figures).
Assuming all WB and Netflix customers move to the super platform, that's a loss for Netflix (assuming the super platform doesn't significantly reduce their costs).
And the $35 might be more than some set of current Netflix subscribers want to pay, so they drop the service, so an even bigger potential loss.
Certainly, I have no desire to subsidize sports fans via a higher Netflix super package.
