Sorry. this isn't correct at all. FreeCAD development is very active and it's getting better every day. I'm using the developer versions because, there are just so many improvements happening to UI and usability. Its development process has also improved a lot since a commercial entity (ondsel.com), run by an active FreeCAD developer. started helping. Just checkout the latest release notes for 0.21, 0.22 and 1.0 if you haven't tried it for a while (sections for PartDesign and Sketcher workspaces are the most relevant, if you just want to design for e.g. 3D printing). https://wiki.freecad.org/Release_notes_1.0

Eventhough I will only use the upstream FLOSS version, I often refer people to https://ondsel.com/blog/ for an extensive summary of everything happening around FreeCAD.
