The APM/ Arducopter source code comes with LGPL (Less General Public License) with it. I am talking about both ArduPilot source code (i.e. ArduPlane, ArduCopter,etc) and Mission Planner source code.
Does this mean the source code can be 'freely' distributed, modified for use in research projects and/or sold for 'commercial purposes', "without" the consent of DIYDrones/ 3DRobotics?
Would DIYDrones, choose to change the license to GPL in future or one of its goal is to ALWAYS keep it IGPL?
