A very good point. Pixar is notably a huge fan of Ghibli studios, which has ventured into less child-friendly fare in the past. But they have always been a big proponent of universal stories, stories which do not demean children nor sacrifice their integrity to subtextually cater to adults. I would bet that they would be making the same movies that they are now, but Disney would not have released Frozen (as a childless 20-something duder, I was absolutely ecstatic watching that old-style Disney musical.)
