Exactly this issue of "you're free to make changes but please don't use the same name" keeps cropping up again and again -- take a look at the case of TeX/LaTeX: https://www.latex-project.org/publications/2011-FMi-TUB-tb100mittbach-lppl-history.pdf https://www.latex-project.org/publications/2011-FMi-TUB-tb10... ("Reflections on the history of the LaTeX Project Public License (LPPL)", by Frank Mittelbach, leading the LaTeX project since 1989.)
