The operation cost of B&C is quite low, the hardware are dozens of low end PCs and neglectable power comsumption per year, or internet fee(probably already paid). B&C can survive with low income in long term.
And BKS holders will listen to the users who may ask for services on forum, of course, shareholders are not deaf.
They will listen the same way corporations listen to their users but hey! it's okay, making profit out of them it's all that matters.
I'm still waiting for the answers of my questions
