Writing for Seeking Alpha, Ed Liston warns that

Needless to say, what Apple is "losing" is just market share. Forget the fact that it makes most of the money and that Google makes more money on mobile advertising from iOS than Android and Microsoft may have made more off of Android so far than Google. Forget all that! If Android has more market share, Google is winning!

Look how complex Google's strategy is, how multi-layered.

Marketing technique wise, Android is a few steps ahead of iOS; it is freely distributed, it works across various hardware platforms.
