The question was a bit assholish, because rant. Fair to call me on it.
Yes, I am aware that KDE audience is broader. Just remembered an additional good product from KDE: kdenlive.
Let me try to put it in a better way: most of the time I have seen Linux in the wild (let's say companies) was Ubuntu/gnome. Even tv shows. And I don't remember ever seeing kde (LiMux aside since it is dead now). I have read that it is sometimes used in some specific industries like chemistry for legacy reasons/apps. Not sure how the automotive industry fits here, but I know they for example use qt, not sure if this extends to kde.
Based on what I have seen and read (which is not all Industries of course), KDE has a significantly smaller user base.
In a non-professional setting, I have exclusively seen gnome.
Not sure how steamdeck fits here, depends on what valve took. Last I read was a compositor. Di they actually use whole desktop with plasmoids?
Can you give an example of de-independent apps that are superior? To be clear: when talking about fitting into a desktop and talking about gnome vs KDE, it comes down mostly to the toolkit. Some examples like vlc could be considered de-independent though even though they use qt
Don't get me wrong, I don't hate KDE project. Far from it. But what they do and what I think they should do differs.
What I completely disagree with is that UX of gnome is wrong. It is opinionated and a lot of us like this 'opinion'. Many people using Ubuntu don't change a thing. Does this fit usable defaults? If things are well thought out, why do I need to tinker with the desktop to launch firefox, office, copy files or consume multimedia? Because in the end - this is what it is about, productivity.
I don't get this hostility statement. They follow a vision - their vision. They offer it for free. And people are upset because they do not work on the vision of that (minor) group?
