The "corruption" angle of this is far more pervasive than just games or game reviews.
As far as I can tell, GamerGate claims to be about gaming journalism ethics and not any media that matters in any significant way.
It was an interesting coincidence that a Jewish reporter in Israel was complaining about media corruption from a different angle when this story was being broken.
No, it really isn't.
Her perspective was that inconvenient facts and stories are not published. Things that don't support the dogma that your editors want to push are suppressed.
You must be either be clueless or a teenager, if you didn't already know that. It's the most prevalent side effect of the commercialization of the news media. I think Slashdot even covered at least one such scandal in the mainstream media and that was many years ago. In that case, a Fox channel in Florida fired two reporters who refused to edit out parts of their news story that were critical of an advertiser (Monsanto). They sued Fox for wrongful dismissal, but lost the case because the courts ruled that Fox had no duty to tell it's audience the truth.
I'm not sure if it's shared ideology driven by the state of journalism academia or if it's mainly more crass corporate considerations but there's a definite group think at work.
I don't think it journalism academia, they despair for the state of the news media. I think it's simply the corruption of mixing profit-seeking in with the activities that are supposed to create the informed electorate. When the news is bought and paid for by the very same people the news is supposed to investigate, is it any wonder that there is corruption? In America, the government can manipulate the media by simply threatening to take actions that will reduce the profits of the news organization unless they carry the news the government wants them to carry. Because the news is a profit center, it's rasy for the government to manipulate these corporations by such simple means as denying access to media scrums or government officials. Things that won't get the average citizen riled up, but could cost the news organization ratings and thus money. Additionally, it's easy for the news corporation to be manipulated by their sponsors because all the sponsor has to do is threaten to move their advertising to a competitor to lobby for certain stories to be softballed. Even worse as time goes by and these tactics are more common, the news organizations learn to take these actions without even be prompted.
Professional journalism at this point can be at best described as a form of political propaganda.
In many ways the words "at this point" make that sentence less true. The term yellow journalism was coined in the 1890s, after all. The corruption of the news media waxes and wanes with the regulation imposed on it. That regulation is pretty loose right now in the name of free speech, which necessarily leaves a lot of room for corruption. There are worse things, for instance, most of the Russian media is pretty much owned by the Russian government so they repeat uncritically everything they are told to repeat which leads to worse media and worse governance.
Unfortunately, I really have no idea how you would go about making the news media less corrupt, other than maybe banning anything that claims to be news from accepting any sponsorship. If they aren't beholden to make a certain amount of profit for the sponsoring organization it becomes much more difficult to manipulate the editors, and through them the reporters.
