I think KDE looks nice but what you said makes it seem like it’s questionable to make a gnome theme over a KDE one? I get that you don’t like it but the person who made this probably uses gnome like you and wants consistency, or just likes the gnome design. So if that’s the case why would they make a KDE theme?
Sadly I don’t know how slave free Tony Chocolonely is, I was reading up about this the other day and they have been removed from the slave free chocolate list due to ties with big coco.
