I don't think that's accurate — the article doesn't dismiss religions at all, it examines theories for why religions have the taboo in the first place.
I'm not sure about you but for me the article seems to dismiss the religion factors in the conclusion towards the end although he started from the religious perspective but the weightage for the religion is kind of fade towards the end. The pork dietary constraint and prohibition from Abrahamic religious point of view, started since the beginning of humanity. But this very fact seems missing from the article's conclusion. And the fact the pork is the common dominator of the dietary constraint and prohibition across three major world's religion dietary constraint, it's the elephant in the room that's not addressed and highlighted clearly the in the conclusion [1].
Since Abrahamic religion is very strict on the dietary constraint on pork that strangely or anomalously ignored by the Christians, but not by Jews or Muslim. But apparently the Christians also ignored many religious ruling based on their own Bible including the controversial circumcision that the other two Abrahamic religions observed religiously (pardon the pun) [2].
If all the Abrahamic religions including Judaism, Islam and Christianity (world's three major religions) do follow and observe the pork dietary constraint and prohibition, recommended and ordained by their respective holy books, we are looking at more than half (simple majority) of the world populations are not eating pork due to religious prohibitions.
