I didn't even read the article - title says it all.  Anyone can cook anything and as long as they do it well, you should be fine eating it.  If done poorly, I don't care if it is "culturally appropriate" (what a horrible phrase) for the cook, it is a badly cooked meal.  Please consider adoption of food from another place far away as a sign of respect for that cuisine and culture, not "appropriation".  What utter nonsense.
