> but calling somebody a regular writer somewhere when they actually just write articles for syndication feels disingenuous.

The author gets to choose where their writing get syndicated to. It’s a conscious decision, for whatever reason they make it: money, principle, or just good friends with the owner. So I don’t think it’s disingenuous to point it that they have chosen to write regularly for UNZ.

I haven’t judged UNZ either way, I’m just providing a citation for the claim that Jonathan Cook writes fro UNZ. Make of that information what you want.
