If the GPL were the creature of copyright law that the FSF proclaims,
or the unilateral contract that some apologists believe, that would be
a real problem. Talk about the Law of Unintended Consequences!
Happily, there is no defect of consideration in the GPL, as the
covenants of return performance (principally the obligation to offer
source code) are non-trivial promises with some value to the licensor.

It's not a meaningless argument, though; there's a doctrine of
reliance that can substitute for acceptance under some circumstances,
and might be used to estop a copyright holder from yanking an
ostensibly perpetual license if all else failed. IANAL, etc.
