Well, the author of the piece is the one that left them out. That doesn’t really change the story. There are many Catholic schools that are in name only, it is not a myth. It is pretty common, especially at the more well known colleges.
Where I went to Catholic college, there was a daily presence of Catholicsm. There probably still is, though I don’t really know. 30 years later, at a well known and respected Catholic college my daughter attended, not so much. In fact, I sometimes forgot it was a Catholic college.
