It's not hard to understand if you think ASR is actually becoming so successful that "victory" over anti-scientific nonsense is within sight. If that happens then the whole "price=quality, measurements=meaningless" industry will collapse and many charlatans' incomes with it... people can get very nasty when they perceive their occupation is under threat.
I don't know that the cause has advanced that far, but we know something is going right if the hardcore anti-science subjectivists are bothered.
Personally I think there will always be a market for subjective reviews even if the "ASR way" took over 100%. People just want to hear the opinions of other people even if they already know the outcome. The subjectivists would only have to give up on some of their unproductive assertions, but the industry as a whole wouldn't change radically IMO. We'd hopefully see a total dying-off of the gold-plated ethernet cables and such, but some people will still want fancy s*** even if they know it doesn't do anything to the sound.
