Google's insistence on using security as an excuse to remove functionality that they want to keep exclusive to their products is so blatant it either is or should be illegal.
No local access kills Google Cast competitors as well as things like this (Nearby Share competitor), Android SMS limitations nearly killed most Android Messenger competitors, removing clipboard access forced people to use one of 2 decent Android keyboards to get clipboard sync back (one of which is conveniently enough developed by Google)...
I have not seen one single instance of Google killing some functionality for security that wouldn't have been easily implemented with permissions instead and that wasn't clearly designed to stomp out competition.
What's the other good keyboard? Since Swype went off the app store I have not been happy with Google keyboard at all. I want to be able to Ctrl+C and Ctrl+V like I could with Swype.
