With a free/standard mobile device (that actually do not exists) you can do whatever you want without limit. Unfortunately OEMs do not want that. And "this" is another Trojan horse to let people think the can run free software hiding the details that their software run in a proprietary jail. With enough time and marketing we will have a new generation of people who find pretty natural download GNU/Linux from an OEM store, forgotten another piece of IT freedom we have till now.
