I think it's simplistic to discount the effect that the bureaucracy, turf wars, and the split-up of the various units as well as trying to push dozens and dozens of different models would have had on the design ethos in the company. It'd say it's more that all these externalities forced the departments to focus on things other than maturation of design to stick around.
