It's becoming harder and harder to deny that Facebook is really CIAbook !
Any two-person contracting shop looking for a government contract needs the same level of clearance that the government employee does.
I wouldn't really call this news.
It's also possible that FB, finding itself the victim of continual PSYOPs, is hiring people with backgrounds in that to help defend the company or needs security cleared people to liase with government security teams on that issue.
I'm getting sick of the cheap cynicism that fancies simplistic, dramatic interpretations over nuanced, realistic ones.
(This isn't to say that FB doesnt collaborate with the government in any number of ways -- just that the parent is a lazy, cheap shot.)
It does nothing to help us decide between the two cases -- they could be selling data to the CIA or sharing cyberdefense strategies, both would require employees with clearance.
