And that is why I think you are misunderstanding where I'm coming from. Again I'm not talking about have D+ Kids and D+ Adults. I'm talking about D+ and Hulu. Hulu will still be its own thing, just under a different entry point under the same app. Again you won't have D+ content being filtered into Hulu and vice-versa.
And the advantage is from a consumer vantage point, having a singular App allows for ease of use. How many App do most people have on their devices, dozens, thousands? Sure they might be used to juggling multiple Apps, but if you make it easier for them its a win. And it garners more good will than you'd lose by purists upset that the Disney name potentially been seen as touching Rocky Horror.
Also come on we're talking about an App here. We're not talking about "The Walt Disney Company Presents Rocky Horror Picture Show". Again people are smarter than you are giving them credit for. You can have brand integrity while still having two separate sets of content under one app.
But anyways, you have your opinion and I have mine. I respect your point of view even if I don't agree with it.
