I've noticed that people tend to think of the surface level of any desktop OS.
They think about the GUI, the command-line programs that ship with it (curl/grep/ls/etc.), the driver support, and the package manager it ships with. These are all trivial abstractions built on deeper facilities.
The farther down you go, the less people understand. Who actually can express the difference between X11 and Wayland that isn't full of weasel words and equivocation? What about mesa, or dbus, or pulseaudio? These are all core components that alter the "flavor" of a desktop Linux system. And yet, all distros basically use the same off-the-shelf components. They only change the higher level GUIs and package managers and stuff.
And people GROSSLY underestimate how much the kernel contributes to the "flavor" of Linux. (I could go on and on about how the GNU GPL directly impacts how drivers are developed for the kernel, or how the small number of core devs are overwhelmed by additions for hardware drivers which move rapidly and break things, and the subsequent vulnerability patches, leaving little time for desktop-focused improvements).
People tend to say things like "the kernel just manages the hardware" or "the kernel is just an interface layer for the hardware" or "MacOS and BSD are the same, only the kernel differs". If only they knew. The kernel is like a seed crystal that defines what can grow outward from there (without massive painful compatibility shims).
Lastly, people OVERestimate the importance of things that are entirely irrelevant to a desktop OS. Just look at how many desktop Linux users are arguing over SystemD vs SysV vs whatever else. Are desktop Linux users really digging into log files, and are annoyed that the log files are now in a binary format? Are desktop Linux users really annoyed that sudo is now part of systemd, instead of a standalone binary that they can swap out? I think the number is low, but the number of desktop Linux users arguing about such things is high.
