Jason Snell:

What’s the world going to look like after this happens?

You know. Round… blue. Pretty much the same as now. I really have a hard time seeing most members of the public turning off App Store protections and installing separate App Stores. Yes, it will happen, but the Play Store is still the place to be on Android, despite its long-time support for sideloading. In fact, Android developers have found that leaving the Play Store and going it alone is quite bad for business. Bet on the status quo.
