A few days ago Samsung announced that they would be adding support for Ad Blocking addons through their official web browser. Of course it didn't take long for developers to jump at this opportunity releasing ad blocking apps utilizing this API. One of the first apps to do so has already been removed from the Play Store. The app "Adblock Fast" was swiftly removed from the Play Store without warning. Instead the developer of the app "Brian Kennish" said he received a human written email letting him know his app had been removed instead. The email reads as follows: The email mentions a violation of section 4.4 of the Developer Distribution Agreement which basically prohibits developers from developing apps that interfere with other apps. Adblock Fast doesn't really interfere with the Samsung Browser since Samsung specifically built APIs to allow this sort of app. So the app isn't really disrupting the Samsung Browser. Is Google upset because the app threatens their ad income or do they genuinely just want apps to operate completely separate from one another?
