I still remember when Netscape had outdated ssl for a few years because more advanced cryptography was classified by the US gov as armaments or something.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.
Which was a clear as day message that "We have ways to decrypt this, but can't yet decrypt that, so please use the one we can snoop on".
Yet somehow we're always forgetting that lesson and surprised when government is found snooping.
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.
So the solution should be to publish the models + weights in a book.
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.
