There is a dramatic difference between twitter hysterics and unleashing a lynch mob (and a woman under duress is a dangerous weapon to unleash on the intertubes), and direct messaging responsible parties. Had she messaged pycon (if she wasn't willing to simply ask them to shut up) this would be a non-story. But, as many suspect, she had to take the opportunity to be the hero of the story to save that little girl on the stage, unless of course that little girl on the stage says something that might be construed as offensive in the future, losing their job and reputation as a result.
