thats pretty standard for north korea

Journalists actually have very weird and, I would argue, self-serving standards about linking. Let me copy paste from an email that I got from a journalist when I emailed them about relying on my work but not actually citing it:

I didn't link directly to your article because I wasn't able to back up some of the claims made independently, which is pretty standard journalistic practice

In my opinion, this is a clever way to legitimize passing off research as your own, which is definitely what they did, up to and including repeating some very minor errors that I made.

I feel similarly about journalistic ethics for not paying sources. That's a great way to make sure that all your sources are think tank funded people who are paid to have opinions that align with their funding, which is exactly what happens. I understand that paying people would introduce challenges, but that's a normal challenge that the rest of us have to deal with every fucking time we hire someone. Journalists love to act like people coming forth claiming that they can do X or tell them about Y is some unique problem that they face, when in reality it's just what every single hiring process exists to sort out.
