I doubt US government departments would appreciate Microsoft control of windows OS and I can't see any other governments wanting their desktops controlled by a company beholden to the US government.

I'd not thought of this. Thing is,once they have control,if they don't like your ad blocker poof it's gone! They can monitor everything. Total control is indeed a scary thing. I have never trusted Microsoft any further than I could throw an elephant and knowing they plan to do this is not reassuring in the least. I just use Ubuntu and I have since XP screwed up one time too many and I could not take it anymore.
