He has said multiple times that he will release the source if he dies, so long as foul play is not suspected in his death. I think for him it's more about being able to "own" dwarf fortress. If he open sourced it, large teams of people might be able to develop it much faster than he could, and if he doesn't really want to manage an open source project, that might end up in him losing control/maintaining a less popular game than whatever gets forked out. It's also widely suspected that the codebase is really bad, and he might not want to manage a clean up of it that makes it 'better' but which results in him not understanding it as well.
