I say this as someone who has run Linux on the Desktop for over 20 years. I do not give a crap about knowing the ins and outs of everything on my system. I have zero interest in learning how bluetooth & Wifi & and all of the hundred other subsystems on my computers work. 99% of the time I want to install the OS, and get on with work.
Sometimes that work means getting down and dirty with a subsystem when I want it to do things that isn't on the normal happy path, but the rest of the time, I want Wifi to autoconnect with a saved password and my bluetooth headphones to autoconnect like a normal person and not futz around learning the intricacies of every daemon and config file in the OS.
It's same reason I pay someone else to service my car. I have fully capable of learning to do it, but I don't care. I have better things to do with my time and money, and there's only so many hours in the day.
