I'm not convinced that's the case. A few years ago I had a laptop with pre-installed Ubuntu and it worked without any fiddling. You certainly can turn Linux into a hobby and try all sorts of variations, which isn't really an option with Windows or Mac. But you don't have to do that.
For me it came with age. I'm in my mid-forties now and although I loved to tinker with stuff, now I want things to "just work". I certainly see the allure of Apple ecosystem. (anecdata but my brother is the same).
Linux doesn't really require you to think about it, necessarily. More that odds are high if you have tinkered with something recently, you are more likely to do so again. Think of it as a reverse lindy number. (And this can be frustrating for folks with automated marketing that feel that they are too dumb. They are, but the dumb approach works rather well.)
To that end, the last time I tinkered with what linux distro I'm using is over a decade ago.
