That is a purely semantic argument. It's also a contradictory one. That article says in the first sentence that they are considering adjusted hues as "shades" or "tints" of red. Using terminology beyond HSV only introduces semantic complexities to confuse the topic.
Wikipedia is a terrible source for this type of thing.
“Pink” was until recently a synonym for “light red”.
However, when it became possible and fashionable to produce more bright purple-red colors, these were also called “pink” (“hot pink”, etc.) by marketers, and now our late 20th/early 21st century concept of the denotation of the word “pink” is considerably broader than 50+ years ago.
