It's both the same and different. The legal question of whether R packages are derivative works of R is similar to the question of elisp packages that use editing primitives are derivative works of emacs. The social question is totally separate. It's obvious OK in the R world to have packages under other licenses. In the emacs world, it's far From obvious.
