>>105645508GNOME devs will ignore standards and purposely GIMP the user experience because it doesn't suit their "vision". A good chunk of its devs are arrogant and standoffish for no good reason. Sometimes they outright lie about facts, e.g "Wayland can't support CSDs".
See the Wayland CSD debacle and how it affected the Factorio devs.
By default it lacks the most basic of features, that any basic desktop UI released in the past decade puts it to shame. GTK4 doesn't have tray-icon support, and they put little to no effort in making Qt applications look good on GNOME.
KDE on the other hand actively listens to users, featureful, friendly devs and puts the effort of making GTK apps blend-in with the Qt ones (where possible, GTK4 doesn't support themes). Also, they are backed by VALVE now, a company that would care about the desktop user experience.
