Their UX research is like Lucky Strike paying someone to find the health benefits of tobacco. They will ask the right questions. I remember two posts about UX testing, one a developer asked like a few random people they knew before making heavy changes. The second one looked promising from a scientific point of view and made me genuinely interested but a couple of paragraphs in and you could already see that it was full of shit.
Repo owners can do whatever they want because they can't afford to lose a single maintainer so leaders just quietly accept that and move on. Source: GNOMErs comments on reddit.
So lots of politics, not a lot of money to be made in the desktop, people are spread too thin. You don't have to deliver a good product when there's no big expectations or your job is on the line.
Is this comment too harsh? I don't know. Red Hat (right they don't own GNOME) is great and did/does so much for Linux/desktop, but many people like me who abandoned GNOME and GTK after v3 have to deal with their bullshit on a daily basis because they control a lot of unrelated stuff. So it's really hard not to be.
