Samsung may have stirred up more trouble than it was expecting when it started blocking ads in its Android web browser. Google has pulled Adblock Fast, the app partner for Samsung's feature, from the Play Store. Allegedly, the title (made by Rocketship Apps) violates Google Play's policies by interfering with other apps and services. That's a bit baffling, since Adblock Fast uses Samsung's own code and had the Korean firm's explicit blessing -- Adblock Plus is using the same code and hasn't run into trouble. The concern, as you can imagine, is that Google might be retaliating against Samsung for daring to hurt its bread-and-butter ad business.
