Paradoxically, I think the people who say they like Hasselblad for the simplicity are not on the margin!
Does anyone really prefer unnecessary confusion and complexity? Would anyone really choose a complex, difficult to remember and confusing piece of equipment over a simple and understandable piece of equipment, when both accomplish the same functions? Most of us just want things to work, and to do the things we want them to do.
The catch is that once you start stripping away complexity to pare things down to a simple set of controls, you've inevitable stripped away something that someone actually does value. I offered a case in point above: I would love a much simpler user interface and design on my GFX 100S, but don't take away my ability to add lens information into EXIF and record voice memos!
If a tool is going to be complex, with lots of control points and menu options, I need it to also allow for simplicity. In other words, let me set things up the way I like, and then let me ignore everything else I don't need. At that point, it doesn't matter anymore whether there's too much complexity if I can ignore it.
