Thank you for the inspiring article and for your comment. I agree that nowadays the fear of harming one's reputation through abuse of their code sounds unreasonable. Leaders of major scientific codes told me, however, that this was their overwriting concern in the 80s and 90s. As an alternative to imposing barriers to entry through fees, some groups demanded collaboration on the first project that used their code (a method that doesn't scale well, but doesn't require writing of thorough documentation, another thing that many scientists dislike). Hopefully, the times they are a-changing.
