The entire story in all its objective context will never be known, and those privy to the story, Horvath and those involved at Github carry more context than we will know. For Horvath, you have to give her credit to go public the way she did. That requires a lot of courage that could have negative ramifications on her career, which could indicate that she was strongly upset about the incidents she described. I don't know her or her motivations, but if she would be playing a pretty risky game if she were to lie. What I will say is that I'm tired of the continual denial or downplay of sexism in this industry. I've seen it first hand, some of drink ups I've attended were a disgrace, and the frat house culture that some tech organizations have cultivated not only make women uncomfortable, but men too including myself. This man-child culture is embarrassing and needs to stop and it's a very real problem.
