It's just an oblique attack on men.
It is, actually, and it's a subtle one. In the face of all evidence, the dogma of political correctness dictates that men and women are exactly the same and should want the same things. Therefore, using this twisted excuse for logic, anything that is done primarily by men must be portrayed as inherently sexist and actively excluding of women. That's what happens when masses of soft-minded people use low-quality logic on "sacred" conclusions they refuse to question.
The idea that it's good enough to have open access for anyone who wants to do something (and when has a wider variety of games been more available than now?) and then those who are interested can participate is anathema to this mentality. There's nothing for them to do in that scenario, no soapbox to climb on, no social engineering to perform, no downtrodden victim to pretend to champion (while actually changing nothing).
You may find this an interesting article. They were going to metaphorically roast a Harvard professor for daring to suggest men and women have different interests and priorities. He hadn't actually done anything to discriminate against women and showed no hostility towards them. He just didn't hold the "correct" viewpoint.
