ASUS is apparently killing the ability to root present and future Zenfone, Updated

This is a most excellent place for technology news and articles.
I don't understand how this move is even supposed to make them more money.
My guess is they're going to slow down the device on new android and block rooting so you can't install your own OS, also, probably doing a lot of spying on the users.
