Forgive me for not trusting anyone who says - Trust me over you for your decisions.
I think you are over analyzing this Colonel Travis. Hung Metro apps will be dealt with he same way standard Windows apps are dealt with. Unresponsive app, Windows notifies you and asks if you want to terminate it. As for the privacy deal, like they cannot already do that. Which they can.

Did I say it wasn't a real concern? I merely pointed out your concerns are not that major. Or limited to Metro apps. Like your privacy concern.
WarningOK guys, let's keep this friendly shall we.
