I think it's fair to say that Disney is large enough that it's not only hard to quantify what impact the company itself has on the storytelling that gets done, but it's also hard say how much of the company is doing storytelling at all anymore.

They've still got animated features, some TV cartoons, some live action sitcoms, but also theme parks and resorts, a video game studio, a theatrical group, a cruise line, a radio station (and a line up of recording artists), cable channels, retail chains, a timeshare program, and a publishing company. Storytelling factors in some of those somewhere but Disney has moved way beyond it's storytelling roots.

I can't even say there's a strong central vision driving their films these days like when Walt was still alive and they were primarily an animation studio or even during their renaissance. When they are storytelling, their successes and failures seem to come down to who they hire or what companies/properties they pick up.

I will say that at least on the animation side they seem to stay out of the way of the creative types and give them the freedom to do what they need to. Disney has some terrible business practices, but they do manage to get their hands on some incredibly talented people who have done some really good work over the years.
