Because Google pays billions to Apple to make its search engine the default search provider for iOS devices, the company collects much more from ads placed on Apple devices than from ads on Android devices.
Google pays apple to be default search engine on iOS; Google does not pay Google to be the default search engine on Android --> Google (the one that doesn't get paid by Google) must be such a looser. Once we have proven that we bravely conclude:
If Google already makes more from ads on iOS than Android, growth in iOS might actually be good for Google's bottom line.
Is this an MBA degree speaking here?
