I know about the KiwiFarms stuff - but never anything so serious about the RetroArch developers. Can you elaborate?
That's just the tip of it though.
TLDR; The retroarch devs had an IRC channel where they would shit on byuu/near all the time, for no reason other than a group of them did it constantly. It was part of their "community".
I'm always wary with these one-sided "X was oppressed by meanies for no valid reason!" and using suicide as a way to enshrine it.
