I'll even help with a starting point: https://daringfireball.net/2019/09/richard_stallmans_disgrac...
I once brought up RMS, in relation to a project a friend was working on, on misc@google, when I worked at Google in my 20s. This was circa 2005 or 2006 maybe. Within minutes I was called out by female engineers for promoting someone I'd come to learn was well known to be pretty sexist. That was about 20 years ago and the details of events shared are lost to me now but the sting of promoting a project he was on (and was later removed from) is still there.
