In any judge's opinion, you'd be full of shit. Judges aren't stupid.
Which doesn't matter, because the WSJ is never going to sue you. But make sure you only consider your justification a personal one, not one that would provide any legal protection.
I thought the problem was that it doesn't matter if WSJ is malicious in this case. Because cfaa is a criminal matter, zealous police departments and district attorney's offices can pursue heavy handed cases even without much cooperation from "the victim" which in this case is a corporation.
