[Fedora-legal-list] FPCA question about 4d waiver limitation

[Bruno Wolff III]

I am wondering why the promise to waive or not assert 4d is only for the
Fedora community?
... "along with
a waiver of the right to enforce, and an agreement not to assert,
Section 4d of CC-BY-SA against the Fedora Community, to the fullest
extent permitted by applicable law."

I would expect people downstream of Fedora to get the same rights as the
Fedora Community?
