The only thing that has changed is society's view of computer geeks, which has evolved from pathetic neckbeards to entrepreneurial wizards. And big surprise, now all of a sudden feminists are concerned about all the sexism and rampant harassment that's supposedly unique to tech.
Every conference I've been to, I've seen men falling over themselves to placate and humor the few women that do show up. Sexism? The vast majority is of the benevolent kind, the kind the feminists themselves constantly advocate for. The kind that makes men watch what they say when a woman enters the room, for fear of triggering another Adria Richards. And the kind that pisses off any capable woman with self-respect.
