Remember how Amazon had sneakily implemented its entire app catalog into its primary Android App and it seemed no one noticed? Yeah, well, Google found out.
If you try to look for Amazon’s app on the Play Store now, you won’t find it. There was a replacement app called Amazon Shopping – essentially the same software but without the app store – but at the time of writing of this article that app also does not no longer appear in the Play Store.
According to Android Police, the removal is due to a small change in wording in Google’s Developer Distribution Agreement on September 25. Whereas before the document would not allow apps whose “primary purpose” was to distribute apps outside of the Google Play store, the document now reads that it doesn’t allow any apps which “have a purpose” of selling outside apps.
Basically, before it was okay because the Amazon app was mainly for shopping, not selling apps. Now, even that’s Google Play Store taboo.
