It seems that the CIA is more embarrassed that their IT has been breached by the Chinese than the death of people that trusted them.
The average half-life of an clandestine agent is surprisingly low, and planned for accordingly.
Something like that is akin to trusting cheap sheetrock/gypsum board and a couple of molly screws to support the weight of some priceless oil painting in a massive ornamental frame.
To see a priceless thing destroyed, but for want of a proper wall to mount it on is insult to injury.
