Well, there is promissory estoppel, of course.  I would also argue that the
downstream licenses are not new licenses granted at the time of acquisition
of copies but prospective licenses granted by the author to everyone who
ever might receive a copy.  I argue that I can grant you a license now to
my work which you may exercise any time in the future should you come into
possession of a copy of a copy.  Since I, the current copyright owner, am
granting you a license now, the possibility that someone else might acquire
the copyright between now and the time that you acquire a copy of the work
is irrelevant.
