Considering the main version of the memo that was circulated was doctored (and the article stated they had doctored it), I wouldn't put much stock into anyone having bothered verifying it. But I don't think that's the reason nobody has quoted the document, it's because nobody bothered to do their research.

"Professional" journalism really isn't doing it's job well at the moment. Everyone just copies the same article contents and titles, and nobody does any actual research. It's quite apparent if you read two articles by similar publications on the same topic -- they contain effectively the same contents which tells me that very little independent research is done.

There was a particularly striking recent example of this, when the director of the movie "The Red Pill" was being interviewed on Australian TV. The questions being asked of her came from people who clearly had only seen the movie trailer, and upon asking whether they had seen the movie (she had sent them links to stream the movie for free several times) they said they "couldn't get it to work". Which means that they objectively were conducting an interview without the faintest clue what the subject was.
