Google is at same position as Microsoft, both of them are not earning any money from this large market share. Not to mention about rampant piracy of applications there.
Let's have some perspective here. Google earns about $40 bil a year, mostly from ads. Microsoft's Windows division still earns $18 billion a year. That part of their business may be in extreme danger at the moment but the only place where $18 billion is a rounding error is the government.
