Media and Entertainment side sucks too. No hate on the actual devs, I know a few of the Maya devs personally and they are competent and want to help, but M+E is like 4% of Autodesk revenue so management doesn't really give a fuck. At least there's still Houdini and Blender is getting better as the time as well.

Freecad is a real no go. Tried it and forced to do something with it. The amount of bugs. And really basic bugs makes using it for professional work a non starter. It basically is a collection of amateur software stitched together with no single part having reached maturity.

Freecad was built on top of a giant library called opencascade. Which is in part the reason why we can't have dynamic or real time modeling. Everything takes triple the interactions to make than in its commercial counterparts.

Add to that the lack of vision and the different fields of work of the contributors makes its development spread all over the place. Unlike blender, it doesn't seem like FreeCAD will achieve a breakthrough milestone.

What is wrong with an existing FreeCAD? It seemed to me that the project is very active

Having used autocad for nearly 40 years, I will say they stick it to their customers pretty fiercely. I still use 2010 with 3rd party software to get it to run on win10 at home. I do a lot of solid models and assemblies as well as technical 2D drawings and renderings.

FreeCAD is impressive, but it lacks an easy to use interface. NanoCAD and LibreCAD are not open source but are free and are both better 2D alternatives.

Edit: LibreCAD is open source.
