Expense. I can't share a link, but I had helped a friend self-publish, and she eventually ended up going the paperback route. She had the option to have the book bound in a similar way (sewn, not glued) but her out of pocket expense would have been 4x higher. Last I heard, she had recouped her costs, but there's still a case of books left.
