It pains me to say it but open source is absolutely infested with insane people. Has been for decades. Take the normal mental instability of programmers (not insignificant) and add in even more iconoclasm, misfittery and the occasional dash of communism. Plus busy-body jannys, plus people who want to be in the software industry but it's literally impossible for them to find a job because they are mental.

How does anything get done? Simple, there's a pareto principle core of dudes at the heart of every project who do 1000x as much actual programming as anyone else and eventually they say something problematic and get ejected.
