This answers "what" the largest contributor(s) to ozone depletion is.
The largest contributor to ozone depletion is nitrous oxide. A recent (2009) article is written on the matter, called "Nitrous Oxide (N2O): The Dominant Ozone-Depleting Substance Emitted in the 21st Century." Nitrous oxide has natural causes as well as human causes and is not regulated like CFCs are.
One of the largest Man-sourced ozone depleting agent still in use is water vapor. This is being produced by aircraft that deliver their relatively tiny amounts of water vapor (and remove some oxygen from the air in the process, which disallows some ozone from being made from it) right up close to and in the ozone layer, fossil fuelled power plants (especially the ones with nice tall smoke stacks to deliver their pollutants far downwind), then as very small contributors cooling towers, fossil fuel powered vehicles, and the extensive networks of man-made lakes. So the "Who" is all of mankind.
There is still some production of CFC in the third world, because:
Nature makes a good bit of chlorine containing compounds, but where Man burns forests or organic garbage, which also causes the release of things like chloromethane, which also are shown to deplete ozone.
