The vast majority of desktop Linux users run Ubuntu (initial motto: Linux for human beings). So one may argue the literal opposite of what you wrote, in that if Canonical didn't invest into making a Linux distro that's accessible to normal people, it wouldn't have the relevance it now does. On top of that, Linux has (or had) a number of clear advantages over Windows that dwarf the presumed upsides of compiling everything from source vs. downloading builds.

There's not much of an argument for adopting obscure niche practices for their own sake
