I still remember when Netscape had outdated ssl for a few years because more advanced cryptography was classified by the US gov as armaments or something. Basically used export restrictions to prevent better security technology from being adopted into commercial products.
They didn't have some secret way of defeating 40 bit encryption; anyone could do it. 512 bit asymmetric encryption was also brute forced by a private entity, albeit at a high budget.
I'd forgotten all the government attempts at controlling crypto like PGP in the early internet days. It is one straightforward way to look at what's happening here without resorting to speculation about this administration's motives.
