Linux distributions are not the worst offenders of over-complicated software. Instead, that would be Windows. Linux is there for the people who need/want to understand and manipulate their system. To a greater degree than any other system around.

No one is recommending Linux software to people who don't need or what this level of manipulations.

What I feel is the greatest abusers of these types of over-complications is Windows. I used to volunteer at a library helping elderly people (plus anyone else that needed help). No one came in with a Linux computer.

What the majority of these people came in with were Windows laptops. Laptops that were just too complicated for them to get a hand on.
