This would be all fine and dandy, save for the elephant in the room, and I may be trying to compare apples with oranges. (can I squeeze in any more metaphors in that sentence?) But doesn't flashing make Knox physically "break" something, telling Samsung we have flashed? Leaving aside the BYOD corporate world where it a a fine, and to be applauded security measure, isn't it a bit "big brother". If I wanted to I could go out buy a Windows PC and install Linux. A year later, if I wanted to I could remove Linux, reinstall Windows and sell it as what it is a Windows laptop. No one would need to know and know one would be affected. Now say I flash my phone, Knox comes in and later I flash an ordinary stock firmware to sell it, I actually sell it broken. It can't be used as a BYOD by it's new owner and Samsung won't honour (illegally in the UK in my understanding anyway) a my warranty. This us what sticks in my craw. I guess I will have to accept it, doesn't make me happy though.
