I have no direct knowledge of the cost breakdown for organizations that publish journals, but I could see how the journal could be the money maker for the organization that then allowed them to perform other duties (lobbying, education, etc... ). My only point is that a print publication could still have the purpose of being a "money maker" and the publisher still be a non-profit.
