Microsoft is an interesting case in that it has lost its influence while growing its market cap. Microsoft is several times as big as it was when PG called it dead 14 years ago[0], but founders today aren't afraid to compete against it or refuse its acquisition offers. Microsoft makes plenty of money, but does not have a great deal of control over what anybody else does.

Microsoft had to make fundamental changes to stop its slide into irrelevance, and the old corporate culture is still trying to reassert itself. There's a battle of cultures happening and it might turn out New Microsoft was a last gasp.
