Yes, sex and tabloid sleeze was the linchpin for all this, but people have been upset with the crappy state of gaming "journalism" for a long time. This is the first time, though, that enough people have been upset about it at the same time that something might actually get done. So yeah, I'm not surprised people are continuing to snowball this as far as it will go and cause as much damage as possible.
These people aren't journalist. They have no accountability. They will accept favors. It's a 'good-ol'-boys' network that has built up into something large enough that they can push away outsiders that aren't willing to play ball, whether they be indie devs or other journalist.
It's a toxic environment that has being growing for awhile and it was only a matter of time until it blew up in their faces. Zoegate just happens to be the story that pulled the pin.
Except this is one instance of a single developer influencing a single journalist, if this kind of thing was rampant you'd have a point. I think most gaming journalists have a decent degree of integrity, the problem is that the mouthbreathing masses are all to quick to jump on the "bought and paid for review!!" bandwagon when a reviewer doesn't happen to think their favorite game is all that and a bag of chips (seriously, read comments on PC gamer etc. reviews, people will trash a review over a few percentage points score), or doesn't bash something the forum hivemind believes to be inferior. I'm not claiming all reviewers have sound judgement, but the situation is blown out of proportion.
