If I remember correctly back in beginning of 1990s there was a discussion in the US about preventing export of encryption protocols, then it was a discussion about making laws where a suspect is obliged to give up his/her key just like in the UK to agencies, and someone even mentioned making encryption unavailable or forbidden by law for civilians. All in the name of "we wont be able to catch criminals if we cant listen in on communications". Up to that point in time, encryption and secure communications was reserved for agencies and those in power, it was not for the plebians. See for example how it went for PGP. I guess a route that US agencies took is to "we will recommend good standards for you, because you know we also need security, but you shouldnt know all those standards and implementations will be compromised so we still retain the ability to spy on you while you wont be able to spy on us and if you do then you're a traitor".
