You're entirely right, but "it is difficult to get a man to understand something, when his salary depends on his not understanding it" certainly applies to the entire "tech" industry, and the app factory in particular. I expect this realization will only become widespread when open-source folks actually fix their software's deep-seated usability problems. The way to do that is not by hiring UX designers or appifying it; it's by thinking deeply about how humans interact with computers and blowing away the conventions that make computers and software unforgiving, hard to explore, and opaque to the uninitiated.
