Remote control?
"..they can request extra data from your machine, which Windows 10 will hand over under remote control if management approves."
Presumably if management does not approve Windows 10 will be smart enough to know this and refuse to hand over any data whether the person doing the requesting is a Microsoft engineer, Bob or Alice?
Of course the methods and security around the methods MS Engineers use to remote YOUR Windows 10 install will never be reversed, hacked or leaked. Or indeed sold to support a habit, gambling debt, lavish lifestyle or simple greed.
Sometimes I wish I wasn't quite so cynical but that's very rare these days.
