There are laws about this sort of thing that have severe penalties attached. When I was in the Navy handling encryption gear I had to sign a paper that stated that I understood that compromise of the secrets I'd been entrusted with could lead to the death penalty. Are you saying that shouldn't be true? Or shouldn't be true for people above a certain level?
Are you claiming that Signal running on consumer iPhone and Android devices where Pegasys and 0-days are for sale is secure?
Are you claiming that it's secure to conduct classified business on a platform where you can add anyone to the conversation without the appropriate documented approvals?
On March 25, CIA Director John Ratcliffe told the Senate Intelligence Committee that when he became director, he was given a phone with Signal pre-loaded. He was briefed that Signal was “permissible” for work use, and “That is a practice that preceded the current administration to the Biden administration.”
I have no idea what the US government's policy is, especially across branches. I'm not American.
I do know that the Signal algorithm is considered among the most secure, and has been considered the safest option for political dissidents, journalists, etc...
I also know some governments do use commercially available messengers (and OSes, and phones).
The CIA director also seemed to indicate that Signal was installed on all their phones.
