Not at all.  Fedora is upstream for Red Hat Enterprise Linux and Fedora
has more packages than Red Hat Enterprise Linux.  Both of these are free
and open source versions.   At this point, you are very very far from
the "open core" business model.  The definition of "open core" is very
specific.

One of the important requirement of open core is centralized copyright
control which none of the examples you cited have.
