I read that article when it came out. This is not a "lighten up honey situation". Adria has every right to be offended and absolutely every right to call out their bad behavior.
I just feel in hindsight it would have been better if she gave the PyCon staff a chance to address the matter before posting pictures of people on twitter. It was her right to take a picture of those guys, its the posting before doing anything else that I humbly disagree with.
