I wonder if the author has ever actually worked professionally on a real team with real constraints and real people all with different ideas about what is right for the product. I'm guessing probably not. Fluff like this is pointless; if doing it the Right Way™ was as simple as following a rant, it would have been done already and the reason to pay designers and developers (namely, to solve difficult problems that usually don't have a 'right' solution) would not exist.
