(1) She publicised herself widely, posted the picture on Twitter, wrote a long blog post on her blog, named her employer directly, claimed her employer backed her actions, has all her contact details and photos on her blog and Twitter. She made herself public.

You don't know much about the guys as they didn't make public claims or announcements.

You appear to be saying they should be identified, named and shamed... which is exactly what Adria tried to do, and look where that ended up

(2) The guy in question apologised almost immediately on HN, a very well written, and seemingly honest and heartfelt apology for making a mistake.

The PyCon organisers took the guys and Adria into a room and discussed the matter at the time, and all were said to have apologised and agreed the matter was over.

If "everyone" thought it was an injustice that the guy lost his job, but felt it was fair and reasonable that she did, perhaps this tells you something. Perhaps it tells you that "everyone" thought her actions were wrong (as the instigator of this affair), and the guy did little wrong

The "reason these things are happening in one direction" is that Adria behaved like a jerk. Quite simple really.

Not a woman jerk, not a black jerk, not a Jewish jerk ... just a jerk.
