This can be said just about any profession working in software. The real issue is that nobody wants to accept that software can be finished especially management - because then you don’t have anything to sell.
I wouldn’t be surprised if there were designers who fought tooth and nail against arbitrary changes. Surprise surprise good UX designers understand UX. But its like the developer who fights for keeping the PHP website because it works.
Sorry i just dont like treatment non-programming workers as something lesser. So many software companies are sucessfull despite having fucked up technology (by programmers). And its sucessful only because they have great design or marketing or sales team.
