Without personal interaction and not to cast aspersions on a person I've not met, John Young has a reputation of being a bit of a firebrand, iconoclast and bombastic figure - however cryptome has operated for many years with a simple policy of publish docs deemed inappropriate for public view...
They intentionally make no judgement on the things they publish.
It is a note of importance however, to realise cryptome - in the case of most of these source documents - are serving as a host rather than linking to the original (guardian/WAPO/firstlook/der speigel etc.) websites, probably as much for posterity as for convenience.
I see little reason to question the veracity of the info provided on this site.
