Wrong, adopting Android wouldn't affect their desktops.... not if they want it to.

Carriers don't release information like that. Sometimes they do reveal their top selling smartphone.... but it will be the iPhone, noone would know if MS is making more money or sales from WP/Android.

Besides it's not humiliating in the least, it's only business.
Was MS humiliated when they revealed they make more money off Android royalties than Lumia sales?? Nope.

The industry has changed. You either lead it, or adapt with it ...or watch yourself fall from relevance as it happened to:
Nokia, BlackBerry, Palm, Motorola, (lost marketshare) LG and SONY.
