I always thought Microsoft would simply make their own brand of Linux (somehow? who knows) that would be all sorts of Microsoftified, which seems easier and better than worrying about Windows backward compatibility by making Windows Linuxified. But the success of WSL would seem to indicate they aren't really in the market for their own flavor of Linux.
