I disagree with the conclusion. My experience is anecdotal, of course, but I'll share. I'm a gamer female with a husband and grown son. Husband is gone now, but the three of us gamed quite extensively together and separately for years, playing various MMORPGs and MOBAs, among other things. My son is exceptionally good at gaming, I am mediocre and consider myself a proud "filthy casual," and my husband was absolute dogshit - to the point I had to leave my chair and go help him by taking over the controls to get him past certain difficult hurdles (and my son does the same for me on occasion).
My husband's ego was never threatened by this. He never took his frustration out on me. Why? Because he was a decent person who was confident in his masculinity.
In the end, lack of skill does not cause misogyny. I believe misogyny springs from the same source as the lack of skill: a tiny brain.
Not saying I agree or disagree with the author. However you being his wife did not result in "female-initiated disruption of a male hierarchy" (their words) so it's not really an argument against their hypothesis.
(Of course your husband being nice and not a dickhead probably also plays a role)
