To be fair, just look what happened to Skype after Microsoft let a designer loose on it: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que... They might have wanted to avoid that and just let their devs dump data into screens without a real design.

I'm not a big fan of what some designers deliver, but sitting down with maybe one or two users and seeing how they try to make sense of the mess that is AWS might have made sense.
