Anonymous can be anyone, there is no side with them. It's a bunch of individuals or any other group who doesn't want people to know. You can't be for or against anonymous, the only thing you can do is judge each individual action on it's own merit.

Based on our principles propaganda that serves to create war and foment a coup is not a good thing, therefor this individual leak IS a good thing. This was such an important thing to get exposed, this is HOW they pushed russiagate and what they are using to foment anger in our country over false narratives.
