#gnome was always been a #microsoft hidden attempt to destroy #GTK and
libre software in order to be a test base for its technologies (C#
it's the best case). GTK it's doomed. Forever. It's just a #Gnome/MS
backend today to test touch interfaces and semi-native #Javascript
desktop software, you are basically betatesting
modern #Microsoft software desktop with it.
#KDE/#Plasma it's just a test suite for #qt5/#qt6
in order to get professional developers for QT which is very propietarily
supported.
Now, the only true libre environment from these corporations left
could be #GNUStep, the *original* supposted-to-be
#GNU desktop environment, not GNOME.
It might look old, rusty, forgotten, sightly enhanced NeXTStep/OpenStep
clone AKA #OSX's dad, but it can look a bit modern with some themes.
This is from the 2010's I think, so it's kinda 'retro' today,
but far better than the default NeXT theme from the 90's.

A least you will be sure that no one would need to adapt it
for coporation purposes.
There's even an #Emacs GNUStep UI port for it, which is for sure the base
for all the Emacs out there for #MacOS.
