tl;dr: Everyone talking about this story is so obviously biased that it makes following it as an uninterested party almost impossible and not worth the effort it would entail.
FWIW, here's my 2 cents.
My brother-in-law is currently producing an indie game. I'm handling all the legal stuff for him, and have been extensively involved on the design and marketing side of things as well, so we've been neck deep in this culture for the past several months. The volume of indie games coming out every day is mind-boggling, so whether one's game blows up or immediately fades into irrelevance is largely dependent on how much exposure the game can attract from indie gaming reporters, YouTube celebrities, etc. Unsurprisingly, since these formerly obscure hobbyists now find themselves in positions of considerable power, the sort of cronyism and corruption one finds in most other opaque power structures has started to crop up here as well.
"Gamers", as in those who not only play but spend a considerable amount of time reading and talking about video games online, are overwhelmingly young, white, male and libertarian. Imagine your average Ron Paul supporter. Thus, news of such corruption among what were once trusted indie gaming sources elicited a strong negative reaction.
Unfortunately, the center of this corruption scandal is a woman, so her defense has naturally been to dismiss all of her critics as woman-hating basement-dwellers. And to be fair, the "Gamer" community has more than its fair share of sexually-repressed misogynistic neckbeards who have posted some truly vile things online. But that's not even close to being the primary driver behind #GamerGate. Just like MSNBC finds a couple racists cranks at a Tea Party rally, or Fox News finds an unwashed entitled hipster to interview re Occupy Wall Street; it's an attempt to discredit a particular position simply by focusing on an extremist fringe that doesn't represent the majority.
