Because not everyone’s as Linux genius? I’m mere a beginner, even though I’ve had to use it for years on various devices, since it’s THE embedded OS of choice for most devices. I’m just not confident enough to do things like building my own OS images or editing uBoot etc. and I don’t think I’m alone when it comes to that. I’m not afraid of a command line, but the thing is, in Linux, if I break something, I don’t know how to fix it and then I have to start over from scratch, which isn’t much fun.
