Except that, in the specific case of operating and maintaining a computer system, they are complete idiots. People have other things to care about and computers only matter insofar as what they want out of them. If that includes (as it did in the 00s) screensavers that will keylog their hardware, they will download the keylogger. And to be clear that's not a value judgment; there are many things about which I am a complete idiot. I don't try to replace my own brakes in my car. I probably could do it. The cost of doing a bad job would be very high. So I stay within my lane.

In computer-related fields specifically, education rarely sticks. Ask anyone who's ever been tasked with educating users about technological opsec. In one ear, out the other. The only sane path forward is to default to high and thick walls. That doesn't mean that you can't opt out, with more or less difficulty. That is the signaler that yes, you have a clue and are prepared to deal with the consequences, and that's great if you are. People are, for the most part, not, and optimizing for you, while hanging the overwhelmingly outnumbering group of normal people in the breeze, is bad.
