The security community in general and privacy activists in particular have resisted giving up the party atmosphere of hacking-as-counterculture the way many tech communities have, and haven't had to because they're not, in general, at the mercy of investors and advertisers. That can cause unfortunate power dynamics in general, and makes sexual politics particularly perilous. That's not really unique to tech; there are a kerfuffle about the American Philosophical Association's smoker a few years back, because new PhDs are there to get jobs and to the people they need to get those jobs from it's a social event. I dread the death of fun gatherings of hackers, because having a community in many ways opposed to its employers is wonderful thing and could be easily lost by having to keep our gatherings professional, but it seems inevitable.
