It sucks you had an experience like that with the community. There are elitists and then just big jerks. What communities often fail at is a groupthink issue where they have a solution to a problem that's extraneous to most people, but they accept it as "well duh, RTFM".

Their project's goal seems to be the adoption of use, broad use and in turn contribution. The problem is their attitudes toward problems that still need to be resolved, and the release management combined with stability is a common problem in much more than just Endeavor's community. You see the issue in Pop!, Nobara, Arch, and even Ubuntu. You even see this BIGTIME in Gnome and to a lesser degree KDE.

A Gnome developer will tell you that you should just use it their way, and not expect basic shit to work, where at least KDE puts it for consideration on their own end to fix or develop.

What I'm getting at in short though is the prevailing attitude of elitism being shitty. That being said, there are people who fall into the "time vampire" group of people who will get pointed toward a solution, but not have the capacity to intuit other basic functions and it pisses people off. Nobody deserves to be treated poorly, but the fine line is out there where it's up to a user to figure their stuff out. From what you describe, updates breaking the user experience falls solidly on their package maintainers fucking their release schedule in the ass, then having an elitist attitude about how to fix it. They'd just as well keep on trucking and treat people poorly for stuff that their own teams broke, to which I respond, fuck those asshole motherfuckers.
