They're classified...if the guy who discovered they were publicly revealed on accident had actually provided them to the Intercept, he would certainly have lost his job, and likely ended up in prison.

The Intercept article says that they gave the documents to at least three (named) experts to review in their entirety, suggested that the Intercept does possess them but decided to publish only a small excerpt.

In terms of the prior commenters assertion about source protection, that was not a factor as the source alerted various of the original parties directly that their material was in public view (as we mention in the story).

In terms of the (admittedly) small volume of original documents we published, all I feel comfortable saying at this point is that we were interested in publishing more, but there were significant legal concerns.

Some of the IBM documents are not classified, as even the article states.
