It's foolish to think that anything Microsoft does will trigger an exodus towards Linux.
Your typical non-technical user, if they decide they're fed up with the latest version of Windows adding more spyware/adware, is more likely to switch to a Mac than to Linux.
your typical non-technical user is totally unaware of any spyware and probably likes the ads, assuming they point to games, weather apps, and celebrity news sites
Every time a new release came out, it was going to be the one that finally would trigger the exodus towards Linux.
Yet the best Valve can do is "emulate" Windows, because not even the studios that target Android with NDK bother with GNU/Linux.
