Ask HN: Why is the AWS console UX so bad?

The AWS console UX is atrocious. I don't even think this is a polarized topic; I've yet to hear anyone opine otherwise. For a company and platform as large as Amazon/AWS, I would think that there would clearly be a positive ROI to investing in quality UX.

Case in point, I switched to the new Route 53 UI a few weeks ago. After using it frequently, I've concluded that it's worse in virtually every measure. There's less clarity, efficiency, and overall feels more cumbersome.

Do AWS product managers just believe their UX is sufficient or even good? Do they want to discourage console usage in favor of API configuration via Cloudformation? Are they simply optimizing for something else?

I'm genuinely curious. What is it?
