It isn't directly stated, but my take is that what set the founder's wife off in the first place must have been that she got wind, through her husband, that Horvath was unhappy with the "boys' club" culture. This account doesn't detail what happened early on in Horvath's time there, but makes it sound like there were numerous relatively minor incidents and a general pattern of behavior. Maybe Horvath said something to the founder, or to someone else who passed it on to the founder, he discussed with his wife, and she decided to make sure it wouldn't be a problem.
I think that's why sexism is a key part of this story.
