The main problem is the way YaST2 is (not) integrated with the modern KDE and Gnome settings. Gnome 40 then screwed things up even more for them as every item is now part of the overview, there ain’t the classical menu anymore.
If you know where to find things it’s great, but right now it indeed feels quite messy with lots of settings hard to find and split in lots of submenus.
It’s a german company again, however currently seated in Luxembourg.
