What a shame...
It started as a childish joke but she was right to complain to PyCon if she felt uncomfortable by this. Instead she decided to publicly shame the men and that is too far.
The guy who made the joke shouldn't have been fired from his job. And she should have apologised to him when she heard he got fired. Now a DDOS has gotten her fired, too...
The irony is that the status quo hasn't been affected at all. Nobody re-evaluates their opinions. There are still extremely politically correct people, there are still people that don't want to make a fuss, there are still people that feel persecuted, and there are still outright sexist/bigoted people.
edit; I hope the mob settles down and that both her and the developer that was fired soon find new employment.
