I agree with this. Imagine studying about web design, accessibility and usability for many years. You feel that you have something to contribute to the design of any app. Then the higher ups just hands you a spec and assigns you to a task to fix this bug/implement this feature without your input. That's pretty damn demoralizing. It will just push you towards caring more about streamlining your own workflow to rather than care about the actual usability of the app. Maybe that's the reason why there is so much interest in the in what workflow to use, what IDE/text editor to use, which languages to program in, etc.
