Hanlon's razor: never attribute to malice what can easily be attributed to stupidity.
Does anyone here think even a decent portion of government officials are tech literate? (I'm not even convinced half of hacker new or half of programmers are tech literate! Instead only have basic literacy and high confidence) There's a few, but I'm not convinced it's that many. The vast majority of Congressmen don't even have an aid who specializes in tech. So do you think it takes any more than someone at the NSA saying "it's encrypted and only we can access it" for them to believe in this magic key? (And this is something we've seen NSA officials say)
Remember, in the senate only 12 members are under 50, 33 are 60-69, and 33 are over 70! In the house 20% are over 70, 43% over 60, and 70% over 50. Only 8% are under 40. Almost none of these people have ever programmed. Just think about how tech illiterate the average 20 year old is (even worse on a technology subreddit!) and we're talking about.
Come on guys. It's a choice between stupid old people and hyper intelligent deep state actors that are acting idiotically. I'd put money on aliens before I'd put money on the later
