And if you just like the good ol' days of gnome 2 then go install mate (Gnome 2 fork) or trinity (KDE 3.5 fork)
Customizability = Complexity = More Maintenance
FOSS groups can’t really afford to have a bajillion options they need to maintain and test compatibility between them. Also, maintenance (especially for free) isn’t fun.
There's truth to this but the extent to which it's true I think depends on how much the system was built customizability in mind.
So for extensive customizability to work without being a serious impediment to development, it needs to be a goal from the start, and most cases it isn't — it's more common for that type of feature to be bolted on further down the road.
FOSS should be whatever the developers decide it should be. It's not up to the users to decide what requirements a piece of software should fulfill.
- I'm not leaning into Gnome (or Ubuntu/Canonical)
- Don't need my desktop to be fun, it should get out of the way for the real fun
- Can't say I've ever used more than 4 desktops
The last two seem particular to individual desktops or opinion.
* Gnome 2 had a lot of themes but since then, there aren't that many.
* Compiz fun is gone.
* Wayland limits the number of supported desktops.
* The desktop is more complicated and it's harder to tinker.
* He believes that customisability (should) set FOSS apart from proprietary software.
