Advancing the queen's pawn 2 squares is a very common first move in chess at all levels. It's disingenuous to call this the beginning of any one of the specific possible openings in the above list.
And calling "It was the best of times" the beginning of a famous Dickens quote hides the fact that it's also the beginning of many other valid English sentences, I suppose.
There is nothing incorrect about the article's statement.
Context is everything, and I think your example only highlights how unhelpful it is to specify that q2-q4 is the beginning of the closed game.
I think most English speakers would agree that Dickens' A Tale of Two Cities is a notable outlier of what is expected after "It was the best of times." That's the exact work of literature that popularized the phrase.
By contrast, mention q2-q4 to any "chess speaker" and they won't be specifically prompted to think of the closed game at all.
Yeah that's bullshit. If you tell a chess player 1.d4 then d5 is going to be one of the first things that comes to mind. Even if they prefer a different response, like Nf6, d5 is certainly going to be prompted.
