A future update to the PlayBook operating system will require users to download and install apps through RIM’s BlackBerry World.
Alec Saunders, RIM’s VP of developer relations, announced the move on Twitter and said it was needed to prevent piracy. Saunders also claimed over a quarter of Android apps are downloaded illegally. In one of his tweets Saunders said RIM was taking action to avoid “the chaotic cesspool of Android market” (Google’s app store recently renamed to Google Play).
@blondeboyofdoom piracy is a huge problem for Android devs, and we don't want to duplicate the chaotic cesspool of Android market
More details are still to be worked out. In another tweet Saunders said RIM was removing sideloading for consumers and said he was “Pretty sure we've got a solution for devs” to test their apps.
