I was pleasantly surprised that the article was such a nuanced overview of the topic, concluding (as is the consensus among archaeologists) that there is no single explanation. We are most confident explaining how pork became the focus among the broader dietary restriction around permitted and forbidden meats, due to the conflict between Hellenism and Judaism.

Beyond that, like all cultural practices, a single psuedo-scientific explanation is uncompelling. I'm hoping that humanity lasts long enough for future armchair archaeologists to look back on our cultural practice and invent pseudo-scientific just-so-stories to explain the weird things that we do.
