Bookstores do not need a copyright license to sell legally acquired
books. By the time they get the book, it has already been copied and
distributed -- they are protected in this case by the first sale
doctrine. This is exactly the same issue that comes up every time
someone talks about GPL enforcement. By granting you a license to copy
and distribute their code, Berkeley has granted a waiver of their
exclusive rights under copyright law -- in particular, the right to
reproduce, distribute, and prepare derivative works -- rights that a
bookseller does not need. In exchange for granting that right, they are
permitted to ask for something in return, and that will be enforceable
(via a copyright infringement action) except perhaps in cases where
such a restriction is contrary to public policy (as, for example, the
censorship clauses covering McAfee anti-virus software have been held
to be unenforceable in New York). Citing first amendment cases in this
context is generally not going to be helpful.

No, but copyright law does say that you have no right to "copy and
distribute" in the absence of a (potentially conditional) grant of
This issue is complicated by the fact that the so-called "BSD license"
is just a copyright notice and was really never intended to be a license
at all. Berkeley's Computer Science Research Group distributed the
Berkeley Software Distributions only to persons who had returned to them
(in duplicate) actual signed license agreements plus a distrtibution
fee. The actual license agreement (as of 4.4BSD-Lite in 1994) was two
dense pages of text and definately a contract.
