A book (on Libgdx) uses one of my repos as a starting point, telling the readers to clone my repo and do certain changes. I've left the repo alone, bugs and all, as I think it's cool that people uses my code. But the authors never reached out or anything, I only discovered it by chance. I could easily by accident have invalidated their whole chapter.
