It's sort of disingenuous to assert that if every member of the press had full disclosure of the status of their relationships with Zoe Quinn then this wouldn't have been an issue, because it's not what this is about. The tricky thing about misogyny in this situation and really as a part of this culture is that nobody practicing it sees it as misogyny, they see it as exposing hypocrisy, or exposing fake "gamer gurls" that diminish their hobby, or asserting their right to do or like certain things, even though in practice it becomes a misogynistic agenda.
The thing that the people focused on Zoe Quinn want to prove is whether or not the critical success of her game and her prominence in the indie scene is a direct result of her choosing to sleep with the right people. However, when you look at it from a distance, even if this campaign to expose a "manipulative sociopath" is successful, it shouldn't logically have implications for gaming media since you can't prove it's a systemic problem because there are no other applicable examples, nor does it discredit her causes because it would just be ad hominem. Ultimately the mission is to prove a vocal "feminist" as a hypocrite, thereby indirectly discrediting her values and her agenda.
That's why for the militant MRAs that started this whole thing, this "press integrity" cause is just a smokescreen, because honestly who gives a fuck what score Polygon gave Gone Home. It only matters because it's relevant to a pre-existing agenda, and to deny that is dangerous. Yes, it's not fair to generalize people involved in an amorphous argument, but it's difficult to deny the underlying misogynistic motivations in light of the direction this thing was driven, just as it is difficult to deny the level of self-importance and contempt shown by game journalists in the resulting backlash.
