> How would we know that the same people complained about code cleanups and not having a file picker?

I also saw some complaints of this form. If I recall correctly they were non-contributors complaining that Gnome devs were dedicating too much time to refactoring and deprecating APIs and not spending enough time implementing features that they wanted.

I'll give you that Gnome developer communication often comes off as defensive, but as an outsider I'm also shocked at the volume and tone of complaints they get -- I doubt I would be able to put up with such toxic users for very long.
