My anecdote is the opposed of yours: they were interested in knowing why something wasn't working, but only as long as you're willing to be patient, talk slowly, and explain any unknown concepts to them, if required.
Insulting them, or just telling them it's their fault something wasn't working would be a sure way to get a negative reaction instead.
Additionally, I don't think these people are stupid, and I'm not demeaning them. They simply do not care to know and that's perfectly fine. I wouldn't demean someone for not understanding how their car works, or even failing to get their oil changed. The computer is a tool to file taxes and shop on amazon for most people, they have a million other priorities in their lives that come before making sure windows is up to date, let alone actually considering its security. It's the job of these companies to ensure their technology can be used safely without consideration by the end user.
