At the point where you've defined the FSF out of FOSS, you've departed the ordinary definition of the term.

Interestingly the FSF also requires copyright assignment for contributions to GCC, Emacs and some other GNU software.

The FSF does appear to prefer copyright assignment over DCOs[1], but as of last year GCC contributions only require a DCO[2].

That is good news, thank you! And I apologize for spreading incorrect information.
