Earlier quoted context omitted.
That's Theresa's claim (if we are going to play he-said-she-said we might as well be consistent). The official response does not suggest that the errors of judgment were unrelated to the subject at hand
What makes Horvath's claim have any more bearing than Theresa's? What happened to "innocent until proven guilty"?
My first comment was in response to onewaystreet's comment "At every company in the world you can find at least one person who hates their job or has problems with their coworkers. I'm not sure they are the person you go to for a fair opinion." The statement seems to imply that it was sour grapes and not an actual systemic problem that led to this situation. My response was that Github's official response admitted that there were problems (explicitly, mind you) but they believed they would win a legal case if it came to it.
My second comment was in response to kelnos's comment 'If you read Theresa Preston-Werner's post (linked above), she claims that the "mistakes and errors of judgment" were completely unrelated to the harassment story, but were discovered during the harassment investigation.' That comment gave Theresa's story much more credibility than Horvath's. Now, this would be a standard he-said-she-said were it not for the fact that Github's reply doesn't refute Horvath's allegations. In fact, Github's reply implicitly refutes Theresa's claim: after all, if what she were saying is true, the official response would have made it clear that the investigation uncovered issues unrelated to the situation at hand.
