If GG had only focused on issues like this, i for one would be cheering them on. But GG didn't come into existence when, for example, Jeff Gerstmann was fired under pressure from a game developer whose game he reviewed poorly, way back in 2007.
They didn't erupt into fury until an indie female developer had sex with a journalist who never even reviewed her game. _That_ was the ethical violation so shocking that it demanded the creation of a movement. And then followed up by throwing a hissy-fit about Sarkesion's and Wu's op-ed pieces. And because there was no rational reason for the level of objections they were raising they resorted to misogynistic threats and insults of anyone who disagreed with them.
So now actual violations of ethics in game journalism are being overshadowed by the group that's using ethics as a flag to wave over their apparent rage that women are involved in gaming and have opinions about it. Claiming to be concerned about "ethics" while focusing almost exclusively on categories of people you dislike is like saying "think of the children" while drafting laws to enable spying on and imprisonment of the kinds of people you dislike.
