- No e-commerce sites charge money on any app stores for users to download their apps since they want the largest audience possible shopping them.

- Google Play only takes a cut of in-app purchases of digital goods and not physical things. Most e-commerce companies would not survive if Google took a 30% cut of everything sold since margins in many industries are in single digits (electronics/computer parts for example are generally less than 5%).

Correct, but I think Kenji's point is that you are buying a Google phone (Android) to have the privilege to download apps from Google Play.

Android market share is at 79%. http://www.forbes.com/sites/dougolenick/2015/05/27/apple-ios...
