> Apple takes 50% of revenue from ads shown on iOS devices

Where are you getting that from? They take a 30% cut on iAd, but few apps use that; for other networks, like Google AdMob, they get nothing.

They don't pay for ads directly. They pay for Google products to be placed on the iPhone. The last estimate I saw was about 50% of total revenue. They pay 0% to place their products on an Android device.
