Honestly I think while this seems absurd if you're relatively knowledgeable about the internet, it's really not something that should be surprising or even particularly shameful? Like, why wouldn't they if it works, is easier to remember, and makes sense to them?

The reasons this is actually potentially bad are pretty deep in the internet wonk weeds, where you get into questions of gatekeepers and provinance of information and it shouldn't be surprising most people don't care about those things: those of us who do have failed to provide them with better tools.

On some level it's a little like saying "my dad sent me an email and he didn't use pgp! Can you believe it!??"
