The tweet itself is arguably going overboard but the accompanying picture is the real issue, this is the element of public exposure which made all this going way way overboard.
It's actually a serious offense and even a crime in other parts of the world, the kind that can send you in jail for quite some time, and on many websites and communities this could get you a ban.
It seems to me it was a threat either of being stabbed with forks or sexually assaulted, neither is acceptable.
This guy has all rights to feel angry about what she did, but this is not a welcome comment and he should probably be reported to the law enforcement authorities.
The police here would be the pycon would acted responsibly and dealt with the issue accordingly.
But the report was not towards the police but towards a potential mob of vigilantes, namely the internet at large and an opinionated group of followers which would probably be outraged by the way the report was crafted.
It would be closer to printing hundreds of tracts and poster and posting them in the neighborhood and distributing them to concerned people hoping someone from law enforcement would see them than reporting to the police.
The employer is all but neutral in this issue, the neutral party is obviously the PyCon staff and they did their part as expected from reasonable and sound responsible people, respecting the privacy of everybody involved.
I wonder how you can not see how her actions lead to his demise.
Definitely not. She's clearly in the abuser position and her reaction was disproportionate and inconsiderate, to the like of baseless sexual harassment lawsuits we've all heard about.
I'd even go an extra step and say IMHO what she did was misplaced sexism as she misinterpreted and misrepresented the situation and would probably not have done anything if women were making the same dongle joke.
