I don't really see it. Yes, affluent people are the one that can afford to "whine". That's because you need a certain level of independence and education to be able to represent a position. Women have been "nice" throughout history. No one cared. Now they are outperforming men and the only reason we are talking about "sexism in tech" is because women are doing so well in many other fields.
The whole premise of the post seem to be that women should know their place. A woman overreacting over being felt up is "whining", while men have been punching people in face over petty things for decade. Some men hesitate to work with women. So? Women didn't have it easy in the past. Now men share the world with women and those that can't work with them won't have many opportunities.
