I think there are a few reasons for the difference.
1) The dangers of diving are more subtle. DCS,narcosis etc etc are not obvious problems to a non diver, whereas the consequences of falling 500 feet into hard rocks are pretty clear
2)Its easier for the diving industry to control the participants. Most people don't have their own compressors. Anyone can walk up to a cliff and start climbing it.
3)Climbing used to be (its changing unfortunately) a non mainstream activity. No glossy marketing brochures extolling the wonders of the spa after a day on the rocks
Good points, especially 1) and 2). I don't think diving used to be a mainstream activity, either though, has only been going that way for a little bit longer than climbing.
