No, they are all ad hominem attacks. She shared ~18000 documents. Doesn't matter who the messenger is at this point, it's all about the veracity of the documents themselves.
Did Facebook deny creating those documents? No. Did they refute statements from those documents? No. Hence statements about the whistleblower are not relevant.
She hasn't shared these documents with the public. All we have to go on is her summary of them, and the documents NBC News has selectively deemed relevant. NBC news has only shared 7000 pages, I'd assume this is probably 10% of the documents. We're essentially being asked to judge facebook when the prosecution is withholding 90% of the evidence.
edit: It appears the shared documents were from a previous leak, I can't locate any of the documents from this leak.
Did Facebook deny creating those documents? No. Did they refute statements from those documents? No. Hence statements about the whistleblower are not relevant.
