The only person responsible for Alison Rapp's firing is Alison Rapp. You can't expect to work in marketing / PR at a major world-wide corporation and not get fired for such activities as moonlighting with a 2nd job taking NSFW pics and spouting off the controversial stuff on social media that she did.
Predictably though, she's become a martyr for the SJW crowd after the initial Kotaku article framed this whole incident as another female in the gaming industry getting lynched by the "he-man women haters" GamerGate crowd. While there's no doubt there are some vile trolls out there, GG has transformed into the SJW crowd's universal boogeyman as a way to deflect criticism from one's own actions.

You know I was always wondering why no one ever used the dollar sign for $ony, but then I realized they have no money so it would be pointless.
