10 million... to the 100+ million users running the OS? They did listen, and they released Windows 8.1 with some changes, but they're also working feverishly to unify their platforms, and provide new services to their users. They need to do that to keep up, and what Microsoft is doing is nothing short of a wonder. They're moving forward for a new era in computing, one in which the desktop is part of (PC, Surface, Phone, Cloud, XBox) the puzzle, and not the whole thing anymore - and for that to happen, changes need to be made.
The complaints were mostly about the removal of the menu, not the button. Putting the button back isn't a sign of them listening, it was a half-assed approach that really suits very few people. As for their "wonder" strategy... well all I can do is point at sales of surfaces and laugh. It seems on the whole the public seem not to agree with your statement that it is anything "wonderful".
