I'm calling BS on that "unintentional angle" malarkey, too.
NOTHING Disney has ever done is unintentional. They're playing 3-dimensional chess in many ways. When it comes to sightlines, they've just stopped caring. You're telling me that when they built an Amazon warehouse-sized building in the park, they didn't realize it'd be visible from Fantasyland? It's not unintentional. It's plain disregard for one of the things that once separated them from the rest. They could've designed it to be better hidden, or at least with a plethora of trees and shrubs to mostly obscure, but eventually completely obscure the eyesore.
As for the lazy engineer comment... I don't think anyone attacked any engineers. I think it's the design that sucks... not the design of the ride, but of the land surrounding the building of course. And if the powers that be didn't give enough budget dollars to design the exterior appropriately, it's still "Disney". We're blaming Disney for this lack of caring about these things... not individual departments within Disney.
