All of Linux? Why? There's a bunch of competing desktop environments you can use instead.
1. Mark all current issues as stale or wontfix when no new work is getting done
2. Partner with/create new software feature that is going to "finally fix the Linux desktop"
3. Expand codebase around new feature, leaving an abundance of cruft and dead code in their wake
4. (YOU ARE HERE) When everything inevitably breaks, they abandon the new feature and blame some perceived open-source boogieman
5. Development falters, funding cuts out, maintainers bail or something else happens that causes progress to return to a standstill (return to Step 1)
I'm a KDE guy through and through, however I think he is referring to a clown on the Arch wiki, not calling Arch wiki members clowns categorically.
Still not very pleasant.
EDIT: well, he did say clowns, plural. Meh. Assuming good faith and whatnot
The absolute disdain and hate the GNOME team has for anyone who uses their software in a way they didn't intend is staggering. Where does it come from? What's it like working on the GNOME team? Is it a cult where you're indoctrinated into believing that GNOME has the one true way and the rest of the Linux community are barbarian hordes? I really want to know.
