One key difference between Apple and Microsoft on this regard is that Microsoft needed such a tool internally: after all given the importance of Azure in Microsoft's ecosystem Microsoft developers need machines able to handle Linux workloads. I know for a fact that Microsoft sees it as a defeat internally that their own developers would rather have a macbook over the company-issued Surfaces or similar windows laptops. So easing the pain of working on *nix machines is a top priority for enterprise Microsoft users. That's not really a huge issue for Apple, they are neither in the business of selling linux virtual machines nor their ecosystem offers such a huge gap to native linux after all.
