Well, as I read this piece she's describing potentially abusive behavior, but not gender related. I read it as a shitstorm of over-intense personalities with optimistic dreams of being the next big thing creating an awful environment for eachother. Somebody of either gender could have a bitter ex-teammate who wants to undercut them.
So I read this as a criticism of the atmosphere of hackathons rather than a women-in-tech issue.
Now, the philosophical question is whether this distinction means I agree or disagree with the author.
