I suspect your colleagues prefer Windows & Mac over Linux not because of Wayland incompatibility but rather because the software selection is better covered over there. E.g gaming software generally targets Windows OS.
It is no secret that Linux software has historically not been targeted at the masses. Add to that, developers who are not interested in publishing software on Linux platforms. You can see why the overall experience might not be that great on desktop Linux compared to Windows or Mac. Even though this might be changing as more users feel comfortable with Linux.
IMO iOS, Windows, Linux all have their strengths and flaws; it would be wrong to compare them side-by-side.
How about "the OS display server, composer and GUI and should be well interested in the OS and perfectly usable out fo the box for all use cases".
My free time is precious and I don't want to play sysadmin on my home computer with Wayland and X11.
Windows and MacOS have their display servers figured out for decades, so the user doesn't have to think about what a display server is, while Linux is still juggling 2 different ones both with their pros and cons depending on your apps and hardware, one or the other might or or it might not.
I work in cybersecurity so everyone in the company is fluent in Linux which we use on a daily basis in various flavors both CLI and a few DEs, yet nearly all of use either Windows or Mac or both at home. Have a guess why that is.
