That's not what I meant, I just took a leap from complaining about the usual advice in the Web involving CLI to the only way to prevent it - as in having some particular GUI as universal, if not more, as CLI, for advice involving it to work.

I mean, for example, in OpenBSD there are no distributions and X server is part of the base system, so they in theory could make a GUI configurator, but OpenBSD configuration is already much simpler than usual Linux, yes, with editing config files. It's simpler than OpenWRT subjectively. That configurator likely wouldn't be in demand.

In FreeBSD they still could have some GUI configurator maybe not completely official, due to there being no X11 in the base system, but still functional. Maybe that even exists.

But with Linux various distributions exist.

If you are talking about user-friendly GUIs fit to do various stuff in a particular distribution, OpenSUSE's one is better than those proprietary things you mentioned. I think Mageia and Calculate Linux too had nice GUI configurations, and maybe OpenMandriva. Obviously Fedora has one, as the go-to "user-friendly" distribution, being from Red Hat and all.

No Linux distribution that I know of has reached the same level of usability, and I think it’s because Linux is a platform built by nerds, specifically for nerds to use.

So you have tried all in the list above and have this impression?

I hate GUI configurators due to my own personal issues with modern UI\UX. They make me anxious. But OpenSUSE's one in particular even for me felt as good as it gets.
