I haven't tried design, so I don't know if I have talent for it or not. But I do have talent for programming, and I don't mind people copying my knowledge and work there, assuming: A) a world where everyone does so, B) credit is given.
The interesting thing about designers is that on the whole, they have less of a choice. Everything that they do is out in the open and - if they do their job well - lots of people see it and want to copy it.
In an open world, we could all be making derivative works of awesome works and advance the state of the art, rather than having to duplicate it first, before advancing it.
