A fair attempt, and probably right, but it is the broader decay that is responsible and the article hints at it. A slow process that takes generations apparently. We talk about the future of metal sometimes, how it looks bleak, but how salvageable is modern Western classical? After all, the bureaucratic reasoning stated in the article should inspire reaction, however meek and minority. It does not. No matter how hard you look you will come up empty.
This is why I think metal was the legitimate spiritual successor of western music.
Edit: To drive home the death, what is the attitude of current and recent-past creators in western classical towards their music? Do they consider themselves an established hegemony? No, they think they are revolutionaries
against an oppressive classical past. An excerpt from a description of The Rest is Noise, a book about this crap, emphasis mine:
The Rest Is Noise takes the reader inside the labyrinth of modern sound. It tells of maverick personalities who have resisted the cult of the classical past, struggled against the indifference of a wide public, and defied the will of dictators. Whether they have charmed audiences with the purest beauty or battered them with the purest noise, composers have always been exuberantly of the present, defying the stereotype of classical music as a dying art.
Tells you the decay is total.
