Is Writergate a technical term or a reference to Watergate?
As a data point: I can honestly say I’ve never heard of Gamergate before this comment, and I am a 31-year-old white male. I did read a book on Watergate when I was in my teens, though.
GamerGate is well worth understanding. While some of the details are unique to the situation, it’s provided a template for right-wing radicalisation that’s been employed multiple times since. There’s also an entertaining “where are they now” aspect where some people have been almost forgotten and some are in the White House. KotakoInAction is still going and has (inevitably) morphed into a bunch of people complaining about the Lūgenpresse.
