I'd compare Bose to a full-size sedan, something like a Toyota Avalon. Toyota designed the Avalon to provide a smooth and calm ride in a luxurious package. So the Avalon's suspension/steering/engine are all tuned for a smooth ride, which is the exact opposite of what car enthusiasts want. An active driver would be happier with a BMW or a Subaru. But if my grandparents drove a Subaru WRX, they'd hate the same qualities that make it enjoyable to the enthusiast.

Bose actively processes the input, which does improve the sound quality to the casual listener. It's exactly what those kind of listeners want. Audiophiles want exact reproduction of the original source, so it's not a good choice for their preferences. But by dissing Bose, audiophiles are doing a disservice to the casual listener, the same way as if I pushed my grandparents toward a WRX.
