Michael Larabel: FSF Wastes Away Another "High Priority" Project.Phoronix, 24. Januar 2013, abgerufen am 22. August 2013 (englisch): „Both LibreCAD and FreeCAD both want to use LibreDWG and have patches available for supporting the DWG file format library, but can't integrate them. The programs have dependencies on the popular GPLv2 license while the Free Software Foundation will only let LibreDWG be licensed for GPLv3 use, not GPLv2.“
