Google have chosen to act surprisingly, removing ad blockers from their Google Play Store, with the reason of "interference with another service or product in an unauthorized manner." This is a very weird move by the Mountain View-based search giant, as one of their main differences against Apple's iOS was that their Android OS allowed you to install any application as long as it wasn't malicious.
Adding onto that list of weirdness, is the fact that Google still allow apps to find their way onto the Play Store that are "for rooted phones only." Is it only a matter of time before these apps are removed too? What does this mean for an app as large, and used by many like Adblock Plus? Well, they can still use the app that they have installed, it just won't be on the Play Store, nor will it automatically update.
You can still acquire the app, and other adblockers, but just not directly from the Play Store. You can visit Adblock Plus' website, which isn't too much of a hassle, but it is a bit of work versus getting it from where you acquire all of your other apps; the Play Store.
