And, historically, they weren't necessarily wrong. The problem is more that all of the tradeoffs and probabilities from history have been thrown at the window, because it is now trivially easy to phish the majority of a population and getting a master key gives you access to hundreds of millions of individuals that you can reach from around the globe rather than a couple dozen that you can get to in person from a particular apartment complex.
Understanding encryption is not the problem. Understanding scale is the problem.
