There's no reason why, for example, her boyfriend at Kotaku couldn't raise his hand at a meeting and say, "Hey, how about this game Depression Quest that my girlfriend made? I think someone should review that. Not me of course, because I am filled with integrity, but one of you should give her some free press."
What you're not getting is that this would be an example of relatively high integrity in the entertainment media. Most of it is much sleazier. A favor for a friend is the cornerstone of successful business. The benefits are intangible in this case, because you [allegedly] can't simply buy that kind of press from that particular outlet. But most "news" is simply something some corporation wanted published, and it often gets reprinted without meaningful comment, let alone changes. The parallel to law is, pretty frankly, disgusting.
The flip side to your argument is that nobody should ever say anything nice about someone they're screwing if they are a media personality, right? But since the internets have made sure that everyone knows who you were inside last night if you are even remotely worth trolling, we all have plenty of disclosure anyway.
That this moment is the "gate" of gaming journalism is deeply embarrassing, and what's more, it has guaranteed that gaming journalism is going to go through another era of embarrassing corruption — not the kind where someone helps a friend, but the kind where review scores are just made-up bullshit. This is what tells us that Gamergate is in fact simple petulance. There has never been integrity in gaming journalism, and you guys (yeah, you've found a handful of women to ally themselves with your "cause", congrats) are upset now because some sex was involved. Usually, it's just the typical ho-hum giving games a free pass in the form of undeservedly high review scores so that more free review copies will show up, which has led directly to the generally pathetic state of new game releases where they don't work for large numbers of subscribers until a patch cycle has passed and so on. The reviewers give a free pass to poor quality and we all "suffer", at the first world level anyway in this case. That's not to say that nobody should be incensed about the lack of ethics in gaming journalism, only that even if all the gamergater claims were true this would still not be the most egregious example of its lack going on right now. You would still have, for example, the entire mainstream gaming press. And by the way, the reason they're not sounding off on this whole rant? They're happy that you guys are distracting the people's gaze away from them, and clouding the whole issue of journalistic integrity with this nonsense non-story. Indeed, if the mass media et al have noticed this flap at all, they must be breathing a sigh of relief that calls for journalistic integrity at the grassroots level are currently being linked with sexism — due to some sexism.
