D+ exists outside of the US only: Everywhere else al things owned by Disney that are streaming are in D+, like ABC and FX series. Also, nobody streams more than children that have Moana in the background, and thus watch it 4 times a day. It makes it far stickier.

Hulu is not long for this world anyway, as Disney has been trying to merge them for years, if you believe investor calls. They'll probably be just one streaming service within the year.
