I found it interesting that the author phrased their critique so definitely, i.e. "it's NOT this and NOT that", yet concluded the article by saying their whole argument was speculative. That said, I do agree with their premise that it's going to be pretty tough to get a definitive answer as to why 0-indexing won out. And their criticism of others being so ready to declare results is apt, if not a little ironic in this case :)
