Tbh, I doubt it. NSA probably gives the exploits to Cellebrite who then packages it as a tool easy enough to be used by a barely tech-literate cop. And even if that's not how it works, the American IC does hire hackers that can find 0days or can reverse engineer Cellebrite tooling. Or the company can always be acquired by a silicon valley ghoul like Peter Thiel.

Above all else, Israel is a valuable forward operating base for our neo-imperialist foreign policy agenda. I highly doubt we're funding the genocide to keep Cellebrite afloat.
