That is NOT at all what people are saying. They’re saying that glueing together 15 different UX paradigms into a program is not as intuitive as something designed before it was coded by people with expertise in exactly that. Design is real no matter how much you don’t want it to be. This attitude is directly hurting open source software.

Not only a lack of designers, but the very concept of them is held in contempt among way too many in the open-source world (like this thread even).
