I'm not saying it'd be to rip people off. Disney has a problem with having bought a ton of sports rights for huge premiums. They have bills to pay. If Dish / Directv / Comcast all switch ESPN to a la carte, Disney loses all of the money people who don't want sports. That'd mean at $40, they'd need around 5 to 8 subs just to cover the potential loss of Cable/Sat revenue.They can't get too stupid with pricing. It is ala carte and people can chose not to buy.
This is a wickedly tight needle to thread.
