Only a Matter of Time
One can be assured that as soon as Microsoft achieves "full parity" of Azure Hyper-V Kubernetes with that of Linux - not if but when, expect that Microsoft will brick the superior functionality of the Linux implementation - with subtle bugs, performance slowdowns, etc, so that the current strong preferences for Linux will swing, even if less noticeably, toward Microsoft implementation to point that Linux will be the also-ran preference.
Remember the - "Embrace, Extend, Extinguish" mantra of Microsoft has never left the camp. Most current techies under 50 -60 years of age, and Microsoft worshipers with little or no good knowledge of Microsoft's in-bred distaste for not being in total and oppressive control, particularly against Linux or any other threatening technology do not fully understand the proven and documented subversive methods in Microsoft's madness.
