This is total panic, isn't it?
Or maybe the last desperate attempt at a stand by the Windows / Desktop faction inside M$ ... "we will get it right, next time, honest"?
But they won't. And it doesn't matter. The world has moved on and desktop operating systems are nothing but a strategic red-herring.
The only question, how can M$ elegantly get out of the desktop game? They can't simply abandon it. Open sourcing it is the right thing, long term, but probably too great a cognitive dissonance for now.
So how to keep conveying commitment to windows. How to "do the right thing" support-wise for users. And yet, start to withdraw, gracefully?
Can M$ do it?
