Do I like it when things are pretty? Sure.
Do I need them to be pretty to get shit done? No
I know that is what drove me away.
Most just want a window manager for xterms.
Designers get bashed because they don't know what people want.
Performance on GUIs gets bashed, because what matters is doing xterms over remote X connections.

Well I can't argue there.
Not much in that department, either. Nothing that beats the proprietary software staples, especially for creatives, that I happen to use: no Cubase, Pro Tools, Photoshop, Premiere, etc. Lots of apps ranging from "close but no cigar" to "why even try?".
I care about CLI tools developed for macOS and Windows in mind, that take advantage of the respective OS APIs.

Not to mention the related GUI tooling.
Where is Instruments on QtCreator, for example.
The GNOME project itself [1] has a lot of projects which compete with what you linked. Sure, Apple has a few billion dollars to dump into development every year, so you have to adjust for scale.
Once upon a time, around 2000-2, I did some minor contributions to Gtkmm.
Qt alone exceeds the feature set, has more GUI tooling, and is multi-platform. That's just Qt, and the same could be said for GTK. I'm not slinging mud at Obj-c and the frameworks Apple maintains, but they are not unique snowflakes without equal.

I can find tons of entries without parity in Qt.
And their current trend to invent a different flavor of JavaScript every few releases, no thanks.
GTK+ is no competition for these APIs:
Because they don't care about stuff like GUI. And it shows.
I'm going to leave it there before the mist descends, but basically as far as I'm concerned Apple couldn't design a paper bag without fucking it up.
Where Linux sucked was in the distros' constant "improvement" of core features that weren't broken in order to be first past the post. For example PulseAudio was introduced before it actually worked with most hardware configurations, and nobody cared about the cool new features it came with. Ubuntu deciding to adopt KDE4 before it was ready for general release was another stupid decision. In fact, I'm basically talking about Ubuntu and Gnome.
Still use GNU/Linux on my travel netbook and of course, some of our servers run it. Last time I used Qt in anger was 5.3, while trying to do a mobile project that I eventually ported to pure native APIs.
Do you know of any other frameworks, besides those that cover all of these ones?
GNU/Linux doesn't have desktop stack capable of matching Objective-C, Swift frameworks both in feature set and related GUI tooling.
