When inventing nonce words that have no real purpose, that conceal more than they reveal, hang your head in shame.

When slamming an author of an interesting article over nonsense, hang your head in shame.

To the degree that the article depends on a silly, invented word that will be forgotten in a week, to the same degree the criticism has merit.

did you read the article? the point he's making is a valid one that in no way depends on the existence of the term "frecency", as long as the concept it embodies is remembered.
