For all we know, this might be a private dispute between two people, and, if presented all the information, Bryan's side might be the side that sounds more reasonable...
While the post fails to directly present evidence, and could be improved by doing so, given the nature of the complaint perhaps simply searching in the bug tracker and related forums would easily surface said evidence.
I was on HN when the Boston bombings happened, trust me, you don't want to let random people on the Internet doxx other people, no matter how smart or righteous the people doing the doxxing think they are.
