I buy a $10 book on Google Books, $3 goes to Google, $7 goes to the publisher. I buy the same on the Kindle Android app, $3 goes to Google, ?? goes to Amazon, < $7 goes to the publisher.
Since Amazon had been selling books on the Kindle app for a while, I assume they made more than 30% to be worth it, or pushed the cost to the publishers? Or probably worked out some deal with Google, which seems a bit unlikely.
Ah that makes sense. I think the workaround was that you could pay without entering payment information, but Google didn't go into every app to enforce this at the time.
