The NSA is angry that their toys were lost because of their incompetence of using a tool that was just doing its job (to find malware) on a system that also hosted their secret toys. They're even more angry that they didn't notice themselves so their buddies from Israel had to tell them. _That_ must have burned.

Since the cover-up among relevant folks failed, and since Russia is slowly elevated to "not really friendly" status again by the US gov't, there's a great opportunity by the US deep state to send a big f*ck you to Kaspersky for their impertinence of doing their job.

Israel is not unaffiliated with the NSA.

They are a trusted ally of the USA and an observer in the Five Eyes alliance.

It's valuable information that can be used to either secure a future favor or serve as a quid pro quo for a previously extended favor.
