If his "open borders"' "free to move" does not include "free to move across borders", then it's a troll piece. If it's "free to move, if immigration law permits", then it's a tautological piece.

Maybe you should try reading the article to see what the article is about.
> To clarify, “open borders” means that people are free to move to find work. It does not mean “no borders” or “the abolition of the nation-state”. On the contrary, the reason why migration is so attractive is that some countries are well-run and others, abysmally so.
You're using a different (and unspecified) definition of "open borders" than the authors of the article.
