I'm giving Appelbaum as much neutral benefit of the doubt as possible...There are definitely some workplaces where such a proposition is so counter to the culture that someone repeatedly and blatantly violating that etiquette should cause warning flags to go up ("when in Rome..."). And there are other workplaces that may have a culture of being more sexually open, and where it's easier to rationalize away someone's behavior by saying, "well, lots of people try to hook up...maybe he was just getting the wrong signals...?"
So what might technically be criminal might not really feel like harassment, just a massive misunderstanding...it's only when more and more people speak up that the "misunderstanding" explanation becomes hard to believe.
That said...there is one other factor specific to Tor project that I would have to guess most definitely dampened the enthusiasm to level criminal charges, no matter how justified: bringing in cops means bringing in people who will search your phone and the accuser's phone (and email, and so forth). There's no way even the most harassed person at Tor Project could go the cops without a lot of personal turmoil and doubt.
Seems to be pretty textbook (not just "in theory", but "as applied in practice") criminal harassment; the only reason that it normally wouldn't be subject to criminal action is because usually between work colleagues, the fact that the threshold for workplace civil liability for sexual harassment is so much lower than that for criminal harassment in this area would result in workplace action resolving the problem before it reached a criminal level (or without anyone feeling the need to escalate to involve police even if it had reached the level it has.)
