Assuming the story is accurate, the problem was not just with the people who bullied the transgendered person, the problem was also that nobody with authority in the GNU project backed her (or at least, not enough people). Therefore it is fair to also blame those with authority that did nothing/not enough to avoid this outcome. The fact that it's taken somebody quitting the GNU project over it to highlight the problem shows that the GNU leadership did not do enough to denounce this type of behaviour. Perhaps there is more to this story than we know so far, but as it stands I can understand Leah's reaction.
