I’m noticing more and more Apps actively trying to avoid Themes and instead opting for the fixed default look. Even some of the Default Gnome Apps. And then there are initiatives like Please don’t theme our apps. Is this the slow death of GTK Themes, and if yes, why?
It’s not that deep lol. They just want to avoid writing extra code to make their apps and toolkit compatible with the wider linux desktop. Being the closest to an “official” desktop environment and having paid volunteers, they have a certain responsibility to make their things desktop agnostic. But they act entitled and really just want to minimize their work. Gtk 3 and below were close to perfect. Gtk 4 and libadwaita are the embodiment of everything wrong with gnome.
