The impression I got from the story I believe she's describing wasn't "discriminatory, anti-women culture" as much as "very bad manager" (to the point of sexual harassment) and Uber not doing anything about it.
Of course, from what I can tell, there's far more than one problem manager involved in all this.
I wanted to see if I can inject some perspective here overall and Her post covers both to a fair degree.
I think that it is hard for us all at times to remember that large orgs can have pretty varied cultures and that some bad experiences don't speak for the whole.
Hoping we can have a productive discussion about culture in this thread :)
