Well per the post, there's more evidence of Google either not adopting or ignoring well known UI design principles throughout Android, in terms of making common functions widely available, consistency in UI, not using a color scheme with two colors directly sitting across from each other on the wheel.

They famously eschew design ideas from design "dictators", favoring data-driven design (e.g. choosing a blue that yields more ad clicks); I wonder if they do this in the Android development cycle or once it is in users' hands.
