Ironass summarises it well. We can still root and flash but to do so would end any warranty and make it so we can never go back to stock. Flashing is always risky, but we all love with that. It's the way they have made it so we can never go back. I've raged about this publicly, and likened it to say "Dell" denying a laptop owner the right to install Linux and maybe go back to Windows to sell it on later. Would they get away with that? I don't think so.
