The main (new) thing is that it was 100% CIA and German Intelligence owned, followed by 100% CIA owned. Not sure exactly how big of deal that really is...
(Edit: other than being a longtime profit center for CIA slush money.)
It's all a bit fishy, especially since it's admittedly sourced from within the agency. A lot depends on if it was an approved leak or not. With the divestment in 2018, and no other really new information, I would suspect sanctioned leak, as there was nothing to lose.
The question is what was gained by whom? And why the timing? There's nothing in the story that's pressing topical information.
Between the Amazon government cloud contract lawsuit, and being 1 week post impeachment, there's quite a few opposing angles that would all seem plausible. Wapo reward for some Agency cooperation maybe? Rabbit holes in every direction.
