I realized that when I wrote this I made an assumption that might not be true. You cannot combine GPL and CC-BY-SA 3.0 code into a single binary or a linked library. So, if any of the files that are licensed under the GPL are compiled or linked as shared libraries against any of the files licensed under the CC-BY-SA 3.0 you are not compliant with the licenses. However, if the files under these two licenses are completely separate than it isn’t an issue. For example, if the code is all under the GPL and some of the graphic files are under the CC-BY-SA 3.0, and if those graphic files are shipped as, for example, separate .png files that are loaded by the binaries at runtime, then this would not be a problem. I haven’t looked at the code for Endless Sky, but I realized that as it is a game this might be what it is doing. Of course, nothing about this changes what I wrote about Unsplash being DFSG-non-free. -- Soren Stoutner so...@debian.org
