Did anybody besides the two parties see the code develop, or does anybody else have knowledge of this? Or is it just his word vs. hers? Do you have any suggested reading to get more perspective other than just the github thread and HN thread? (really asking. these aren't rhetorical questions)
Reading the thread, I do think there are a lot of opportunities to read in confirmation bias. For example if I start reading that thread with the idea that Justine is coming in to hijack the project and make herself the hero that it needs and deserves, and to get her initials embedded in there as a permanent tribute to her own glory, I can see that. But if I read it as her coming in with cool work that she's excited about, and had to come up with a new format and couldn't think of a name (naming things can be really hard) and just stuck in one of the first things that came to mind (or even used as a placeholder prior to discussion), I can see that as well.
I absolutely don't want the truth covered up, but I also don't want to accept as true things that aren't true, especially where the implications are toward somebody's character. I'm a big "benefit of the doubt" kind of person.
