It's not ZH, to be accurate.
Article is written by William Craddick who published it on Disobedient Media:
disobedientmedia.com/2019/05/is-this-intelligence-group-responsible-for-the-q-anon-conspiracy-theory/
The Tylers just re-posted it.
Haven't read the article though, so I can't confirm/deny if it is indeed an attack.
