The same thing that happened before: you either chose to install it and side-load it or you don't. Side-loading is something that only a very marginal minority of people do. I don't understand the fearmongering. Anyway when you sideload an app on an Android phone, the APK is scanned to check if it's secure to install. Permission wise, nothing changes. Policy wise, it means no Apple tax and maybe some publisher will be able to cut prices, to the users' benefit.
