Android's been locking down on this for a while, but it really feels now like they're moving to a world where custom ROMs are cut off from much of the Android ecosystem, and official ROMs are completely locked down and inaccessible even to developers. These changes are important for Android to ensure it can protect average users from serious risks and attacks.
