The main developer of a popular rust framework (actix) was bullied enough that he quit and only when he quit did a bunch of people come out of the woodwork to support him - not before.
That situation was more complex - it started when a security researcher found a flaw in the codebase, raised that concern including a patch to fix it with no negative impact on performance only for the patch to get rejected for being too “boring”. The bullying was a big step too far in that situation, but the maintainer of actix was not fully blameless by dismissing others honest work for no good reason.
