Me : Why is that important? It's all about perspective. The purpose of mapping isn't to force one particular perspective on others but to encourage the discovery of other perspectives. It's the only way mapping will evolve.
Me : What about it? There's a reason why mapping is creative commons share alike. It has nothing to do with ownership and everything to do with encouraging a field to develop. Think "small piece of a large pie rather than large piece of a small pie"
Me : It's a journey. Relatively quick to start but a lifetime of learning will follow. I regularly drop bits into the community to push it along but it's a vast subject and we have to take everyone with us.
