I know first hand that Nokia top and middle management understood nothing about software development or quality. The tools and practices used in the whole development were horrible. After a couple of years they just drowned in bugs and new products came slower and slower, failed projects more and more frequent.

I have no idea whether it's equally bad at Google/Android or Apple. I have the feeling it's not.

I don't think China really dominates in software world-wide. Xiaomi seems more like an exception to me. Hardware is a different story.
