I think it's the result of a mindset that some people have regarding bands they personally like a great deal. It seems like they believe that a band and its audience are necessarily involved in a two-way relationship of a certain type, that exists whether the band or the audience acknowledge it or not.
I personally don't feel like BoC owe me or their other fans anything - no news, no new album, no studio update. If they want to disappear completely, and let's remember who these guys are, please, they certainly can and will. They clearly have an amicable attitude towards their fans, despite having been given many reasons not to as their stuff got leaked and released, but I don't think they make music for the fans ultimately, ultimately I would guess they make it for its own sake and for the sake of exercising their own artistic livelihoods. And I would guess that BoC don't share the notion that some of their more energetic fans have, that their music is a community good so amazing and so important that not to proliferate it year after year is to do their fans a disservice or insult them. From what little I know of their attitudes from reading interviews, my guess is they would be more like, "It's art, it's not irreplaceable, make your own, it's fun"
