You do realize that this Harvard member is not just attacking Anita but also the supporters of GG ?
He states
" Yet this is the modus operandi of GamerGate’s detractors, and its supporters. They are the nearest thing today to engineered narcissists. For they are so slavishly conditioned and socialized to one-sided rhetoric, to invoke Meg Wolitzer, they have butter, but no bread"
So we are all idiots to him
If you read the links mentioned, you will see that he is attacking Twitter as a communication medium, since it supports narcissistic behaviour. Furthermore, the first paragraph is only about just that. The rest is about the intellectual laziness of Anita ideas.
TL;DR-version: She is a champagne-marxist without depth.
