That's totally a valid point. I wish more men would speak out against this and, honestly, that it is not used to diminish the equally valid point of sexism in technology.

But we have to understand that in those situations it is not oppression. And that is a key point. Men are not oppressed by society when they are discriminated, because by-and-large, men make more money, have more opportunity, stay within their industries longer, are (perhaps due to last point) promoted more often, tend to be selected with a gender bias to speak about their subjects. Women currently get more college degrees in general today, yet the gender pay gap remains. That's evidence of systemic oppression. That's why we can say men at large are not discriminated against.
