The only way "use their tactics" is to archive all the insane shit these SJWs say. Maybe one day it will actually matter, like for James Gunn.
Despite the very public, archived and documented #KillAllMen rhetoric from people like Ashley Williams, CoCs will not be enforced upon them, in fact they'll get promotions. You can even see this with Sarah Jeong getting hired at New York Times.
For now, they can do whatever they want, say whatever they want, and their demands will be catered too.
The one silver lining is that this is a reduced/older version of the Contributor Covenant. It doesn't include the newer rules where it essentially states that it cannot be used against women or "minorities".
