The document presents two fictional business cases put forth by a public sector body for either opening or restricting access to its data. The first argues that opening data increases accountability, helps businesses and the economy, engages citizens, improves efficiency at little cost, and facilitates collaboration. The second instead prioritizes limiting transparency, asserting producers know best, charging fees, and making money the primary goal rather than public benefit. It is revealed in the end that these cases are fictional and no real agency would use such arguments against openness.
