To create something like the GNU project, or OpenBSD, or Linux, takes serious levels of commitment. You really have to believe in it, and to a degree, you have to _will_ it into being. Along the way, you need to explain why your crazy idea is worth all the sacrifice, discourage those who would distract your team members, maintain your own and the team's focus through years of not actually having the thing you want in any useful form, etc, etc. You have to be an unreasonable person to take it on, and then continue it.
There are people who become "fans". They can be even more zealous than the project leader(s). Maintaining direction (aka control) of a horde of over-zealous fans takes aptitude and patience. It's easy, I think, for projects to devolve into vitriol, and denigration of those who think differently, even if it starts out from a good place.

Well, we also enjoy the issues. When you talk to them they are extremely uncompromising in practice and extremely tribalistic. I think “tribalistic” is maybe a better word for what I feel is an issue. “Not invented here syndrome” reigns supreme in open source and in general it's full of extreme fanboys who aren't willing to admit anything is wrong with “their tribe” and aren't willing to acknowledge any issue whatsoever and defend everything to the death.
The opposite is also just as true though. Many of the users and figureheads will believe everything is wrong with “other tribes” and refuse to acknowledge any of the merits and good ideas.
Proprietary developers have no allegiance but to money and there's something to be said for that. They just work for a company because it pays them and will switch to another company when they get a better contract there and in many ways that makes far less loyal and thus level headed about many things when talking to them.
