Funny how they publish this on their own website given as they still don't officially confirm the operation according to the other article linked above
Well this is just a set of press clippings, and you could consider it's just part of their open-source collection of things relevant to them.
It's neither an admission nor a denial. But I get your perspective on it being funny, and it is. Just like there's data in there on UFOs and aliens even tho CIA doesn't officially confirm those.
I think the FOIA reading room is basically like a library of interesting things. I'm surprised more people don't see the value of the stuff in that library. It's one of the best digital collections online, I think. And the search through scanned PDFs is pretty great...I suppose you can expect that from an intelligence agency.
