Disney probably took that into account, and decided that the demographic buying DisneyOnDemand (or whatever they call this) isn't going to overlap much with the demographic visiting yohoho.warez.se
I'm not so convinced that true though. As I said in my post, I know plenty of people who have Sky / Virgin Media as well as Amazon Prime and/or Netflix subscriptions but who do also pirate content when they can't find what that want on the aforementioned.
There are only so many video subscription services a person is willing to pay for.
Maybe Disney have a compelling enough catalogue to convince people to switch away from an existing streaming service (which is what I think they're banking on), but I'm not so convinced that will happen at scale either.
