Not at all. Newcomers want intuitive UI. And gnome is really that.
Examples:
One unified settings app. Containing all the settings that as a average user needs. It’s always at the top right corner.
Change the wallpaper? Top right corner -> settings
Add a network? Top right corner -> settings
Extend display to projector? Top right corner -> settings
It’s not weird at all.
What would be a better starter DE then?











Like KDE? It would be a lot more complex. I would fear giving KDE for newcomers. It’s basically windows 98, but with frosty glass themes, fragmented apps.
Or Cinnamon? You upgraded to windows XP. Congratulations.
Deepin? Looks cool until you try to use it.
Xfce? That’s stable and fast. But would you advertise Linux as that outdated?
Cosmic, still early.
Budgie, maybe.
I really think gnome is the best default.
Nevertheless, It’s you mixing intuitive and familiar. Moreover, people who give Linux a trial, they wish for something different. And they really like Gnome from my experience.
