"... what those thousands of pounds are is called the cost of doing business. I do also think that it is quite incorrect to air that "do it yourself" phrase every now and then. We readers are the demand, and the publishers are the supply."
Nevertheless. I see a moral difficulty in condemning others for failing to take a risk that I would not take myself. You might however be able to exercise some influence on a publisher if you were to start a crowdfunding/subscription initiative — if enough people to sign up you demonstrate that the demand is there. This has been done with music and films but I don't know if anyone's tried it with books.
