QA needs to be paid. Largely nobody is doing QA as a passion.
As for UX, if these are the same wizards working around Windows/mobile/web, then please keep them away by all means necessary.
QA needs to be paid as does programming. I imagine some people have a passion for it and could build automated qa tools around open source products. Say a gui tool that automates clicks on kde or gnome widgets. That would be quite a challenge in itself.
As for ux, open source is not a job. Ux folks are told my product managers to enshitify things on daily basis.
I imagine open source can provide a safe haven form all that and let people run wild beautiful ux and uis. Imagine someone working on the ux of a linux distro aimed at making onboarding of casual users easier.
Imagine a group of people putting together a nice set of guidelines for ui and ux similar to how apple has guidelines.
I think these are two areas where linux (distros) have gaps.
The simple part is UX people working with UX stuff, such as GTK or QT themes. The hard to impossible part is getting a typical open source UNIX desktop to look and behave as cohesive as Windows or Mac. It's a technology issue and not an asset issue.
As for beautiful UIs QT has made a step forward with the Qt Quick and Qt Designer which allow a more UX workflow for the UI as opposed to old school dialog/form design.
