The irony is real. The only selling point for macOS right now is the unparalleled vertical integration, iCloud+ iPhone + Handoff etc. And also beautiful hardware that usually just works.
Yeah, as an iphone user it's the handoff stuff that keeps pulling me back to macOS. It's really handy, especially with cross-device cut and paste recently. However, I've also been using WSL and it has really impressed me. I need to check on the current state of similar windows<->android stuff before my next round of purchases.
MSFT are not the only ones in the Linux ABI emulation game. Illumos and FreeBSD are doing it too.
The Linux ABI is still a moving target, but it's moving much more slowly than a decade ago, so you can now expect every OS to start emulating it (warts and all).
