Apparently FreeCAD is nonfree. It's based on Open CASCADE whose license is
apparently nonfree by FSF standards:
https://en.wikipedia.org/wiki/Open_CASCADE_Technology
"The Fedora project does not consider[10] Open Cascade to be free software
(free as in freedom) according to the Free Software Foundation definition,
and therefore does not include it in their distribution."
http://www.freecadweb.org/wiki/index.php?title=License
"In the Fedora project OpenCasCade is listed "non-free". This means basically
it won't make it into Fedora or RedHat. This means also FreeCAD won't make it
into Fedora/RedHat until OCC is changing its license."
Contrary to Arch, Parabola doesn't include neither Open CASCADE nor FreeCAD.
Trisquel on the other hand includes both.
I don't have time right now to research more on this, but it seems that Open
CASCADE and FreeCAD should be removed from the repos.
