Except that a huge amount of the world runs on cryptography designed by him, because all the standards committees and government orgs are somehow less trustworthy than this "asshole".
How someone reacts to him can reveal whether that person is someone who thinks they are smarter than they really are, a personality type that is common amongst software developers. These are the type of people who cannot admit when they are wrong, and will never admit that they are incompetent. Arguably, it is because of such people that we are drowning in crappy software, and even worse, that crappy software is popular.
IMHO, djb is on the side of the user, whether intentionally or not. djbdns allowed me, a user, to take control of DNS on the networks and computers I own. The philosophy of BIND at the time felt like "DNS is for DNS experts. We're experts. Do as we tell you."^1 I also learned nsd so I do use BIND zone file format. But I never became a BIND user.
1. I see a parallel in the context of "certificate authorities". Nothing wrong with "CAs" in theory but in practice, i.e., commercialisation of certificates and browser-centricity, the system reeks. Pay to play, or at least mandatory third party intermediaries, and generally user hostile.
I think it might be dangerous to elevate people in this way. Probably djb is a human, who doesn’t represent a dowsing rod for your evaluation of the world.
