For one thing as far as i can tell we're dealing with the wife of a founder that has delusions of grandeur and a founder who is easily manipulated.
The very few allegations of sexism like some employee asking her out and the passive aggressively harassing her will happen in any environment not just in technology it's just the guy not being a man and facing the rejection. All you can say to him is grow up.
I also don't see anything wrong in the guys looking a the girls playing with the hula hoops If the girls minded the wouldn't have done it what right does she have to judge them.
