@mcepl #Gosling #Emacs originally essentially public domain (like predecessor Emacsen by @rms). IINM @rms knowingly used Gosmacs code
@mcepl Incident was key event leading @rms to create #copyleft I believe, but I also theorize it led to concern about copyright ownership

probably already aware, that is
