GamerGate was about ethics in games journalism roughly as much as the Arab Spring was about a street vendor having his cart confiscated.

That was their initial spark, but it kicked off a ding-dong battle for years. You could argue it's still going today, given places like /v/ and ResetEra are still fighting it, games like Dustborn and Concord are pilloried, and the "Sweet Baby Inc. detected" Steam curator exists to list games that have taken that company's advice.
