Oh, I get it now. I guess I agree with that, then. Though before you reach "perfect, ideal usability", I feel like it's still subjective. Linux is currently more usable to me than Windows or macOS.
Also I think we could debate on the "footguns" idea. Many people will say "we should not allow the user to do that because it is a footgun" for many things that I barely consider "advanced usage" and that I actually want. Does making it simpler at the cost of removing possibilities count as making it more usable, or less?
