The only examples I could think of or was able to find in a brief internet search were Blender (3D animation software that had its source code bought from creditors after a crowd-funding campaign) and Warzone 2100 (Game that had its source code released after a successful petition). With those two examples of different strategies in mind, have any of you ever participated in any efforts of this kind, and what did you learn from it that may be useful to someone else attempting the same thing? Even if you have not participated, do you have any suggestions or ideas that may be useful to such an effort?
