Gamergate or GamerGate (GG)[1] was a loosely organized misogynistic online harassment campaign motivated by a right-wing backlash against feminism, diversity, and progressivism in video game culture.[2][3][4] It was conducted using the hashtag "#Gamergate" primarily in 2014 and 2015.[a] Gamergate targeted women in the video game industry, most notably feminist media critic Anita Sarkeesian and video game developers Zoë Quinn and Brianna Wu.[b]

TL;DR - there was nothing, and then internet fascists got big mad about the nothing.

The whole artificial scheme was called out before it started, because the victims-to-be had moles in these idiots' back channels. It did not matter. Conservatives do not live in reality.
