Back then one could purchase books on Kindle iOS app going through Amazon's payment processor bypassing Apple's payment option. There was quite a big furore around this. After a few back and forth they reached a compromise of sorts where Amazon removed the book purchase flow from Kindle iOS app and Apple was OK with letting customers download and read books purchased outside of Apple ecosystem (through Android for example). At one point, Apple took an extreme position of only allowing books purchased through their payment option to be read on Kindle iOS app. This was obvious not acceptable to Amazon.
