"Yes. Free money; they've already paid the wages to create the product."
Well, it's not really free money - they have to pay lots more money for the print run. Paying the authors and the layout people is, as I understand it, the least expensive part of publishing.
They may (Prophets forbid!) decide not to throw good money after bad (just an expression - I don't in any way regard paying the creative staff a bad thing!!!). I hope they decide to go ahead with the printing, but when bean-counters rule the roost nothing is certain.
