That's not exactly the conclusion of the article. But I understand your belief.
I don't believe it, I know it.
The word "pope" is defined as "the head of the Roman Catholic Church." Peter was the first temporal leader of Catholics. There is an unbroken succsession of popes following him.
Trying to redefine "pope" in a manner to exclude St. Peter is similar to the attempts to redefine "marriage".
Now, if some Christians want to claim that there was nothing special about Peter, compared to other Apostles, then go for it. But you can't try to redefine terms in order to do it. Peter was the first temporal leader of Catholics, the temporal leader of Catholics is called the pope, therfore Peter was the first pope.
