Time is very precious. As someone who's done the investment into both desktop Linux (Openbox) and MacOS, the level of effort required to get something useful is way different. MacOS has a very gentle learning curve so it's easy to switch and be back in business, getting work done. Linux OTOH is less of a learning curve and more of a learning cliff. I've got the exact right monitor setup I want on Linux, but it required learning xrandr and writing a shell script because none of the GUI frontends could get it right. With MacOS I kinda just have to accept whatever it gives me as good enough. Thankfully it usually is though.

Point is, because desktop Linux isn't a little bit of effort, it's a lot a bit of effort, so I can't fault anybody for not putting in the effort to learn it whilst there are viable alternatives. Which includes ChromeOS these days, to throw a curve-ball in there.
