Vast majority of people, technical or not, do not want to sit there and fiddle with their OS. They want it to just work, and have a consistent experience, from one release to the next, so they can get work done, or view pictures of their grand kids. The number of people who want more than that is a statistical rounding error. HN and other forums like it, have such a huge echo chamber, that they lose site of reality.
"Vast majority of people" want it _their_ way. And this is where enterprise-y software fail really hard. They think that making software as dumb as possible they will please the dumb.
In the real world it doesn't work like that. Dumb users don't know how to tweak things but they know that they can ask other people to help them.
