Weren't you the one who was arguing that they had followed them?
In a themed environment -- even one that's themed in a unique way, like Future World -- such a large, looming, unthemed box is inexcusable. That's the crux of it. Whether it bothers you personally or not is basically immaterial, it's not good work.
Here's the real test -- as guests, do we want to see Disney build more bare, blank buildings like this, or less?
Remember when Disney went back and added rockwork to the corner of Enchanted Tales with Belle after New Fantasyland opened because they noticed guests could see a corner of the showbuilding?
(PS: This is a really good example of where Go-Away Green works, because it's trying to make a sliver of building blend into the space around it -- and even THEN they went to the trouble of adding more rockwork after the area had opened officially, because it didn't meet their standard.)
They could and should have done better.
