I thought this was going to be about people who took the Steve Jobs route of design: "I know better than you, you'll use my design and like it, or go to hell."

People see Jobs' success in design and think they too can be successful by being merciless dictators of their design vision. Unfortunately 99% of people don't have Jobs' talent and they end up messing up their projects. (Gnome 3 and Unity, I'm looking at you, though this terrible phenomenon isn't isolated to those projects.)

37 Signals is also guilty of spreading that mindset, perhaps more so because they aggressively blog and write about it all the time and because they are (or at least were) startup darlings.
