It seems Google's issue with Adblock Fast was more technical in nature. The adblocking plugin has been reinstated on the Play Store. So, if you use Samsung's Internet Browser and running Android 4.0 or higher, you can install the plugin yet again. But if you're on Chrome and want to access the adblocker, unfortunately you won't be able to use this.
