\section{GPLv3~\S10: Explicit Downstream License}
% FIXME-LATER: this is a punt: need more time to write!
GPLv3~\S10 ensures that everyone downstream receives licenses from all
copyright holders. It really is a generally straightforward section.
% FIXME-LATER: link up this paragraph to above sections.
GPLv3 removed the words ``at no charge'' from GPLv2~\S2(b) (in GPLv3,~\S5(b))
because it contributed to a misconception that the GPL did not permit
charging for distribution of copies. The purpose of the ``at no charge''
wording was to prevent attempts to collect royalties from third parties. The
removal of these words created the danger that the imposition of licensing
fees would no longer be seen as a license violation. Therefore, GPLv3~\S10
adds a new explicit prohibition on imposition of licensing fees or royalties.
This section is an appropriate place for such a clause, since it is a
specific consequence of the general requirement that no further restrictions
be imposed on downstream recipients of GPL-covered code.
