GNOME. Won’t say I don’t hate it sometimes but every time after a few weeks using anything else I’m back to gnome. The polish and smoothness are unparalleled, and I don’t really customize a lot. I did used the Plasma 6 beta and seemed great even if it’s not my preference of design language, but haven’t tried since. I should give it another go.
Not about code security (even thought that is certainly important by itself). Sanctions are about political and economical isolation, is not that you don’t trust their companies, is that you want to unplug them as a punishment.
