Someone's opinion on the current state of the gaming industry is exactly corruption. Digging into other people’s private lives in order to gain that kind of information isn't a good idea either.
I don't think that people aligned with GamerGate are even that concerned about ethics in gaming journalism to begin with or at least there is this gap where one group is actually advocating ethics in game journalism but the other more interested in eliminating the SJW aspect of game journalism which is not corruption.
I also don’t think gaming journalism is all clean either. There are certainly problems to be had there but it’s more to do with publishers who are going to companies like IGN with bags of money so that they can promote their game rather than anything else. No actual evidence of that I’m afraid though, just on how obvious it seems.
