That's a reference to the "Gamers are Dead" articles that helped cause GamerGate to take off.
Basically, a bunch of hipster fucks were passing around a study by a insane cat lady communist that Gamers don't believe in identity politics bullshit and believe in meritocracy and therefore, the Gamer "identity" needed to be destroyed so they could be replaced with a group that would let insane cat lady communists dictate terms to the industry and use vidya to indoctrinate kids into communism.
No, really. The crazy communist was Adrienne Shaw. Go read some of her insanity, it's amazing. She did an academic study and published two papers with the exact opposite results based on what opinion she wanted to push at any given time.
Anyway, this is basically the Bell of Lost Souls trying the same damned thing with Tabletop.
They couldn't guilt you all into accepting the inherent need for diversity hires at GW and the like, and you kept telling them know when they told you you were sexist pieces of shit for not wanting Female Space Marines, therefore, they're just going to demand GW migrate away from tabletop so they can infest that segment of the hobby until they can force the changes from that direction instead.
