-\section{GPL \S 7: ``Give My Software Liberty of Give It Death!''}
+The first sentence in \S 6 ensures that as software propagates down the
+distribution chain, that each licensor can pass along the license to each
+new licensee.  Under \S 6, the act of distributing automatically grants a
+license from the original licensor to the next recipient.  This creates a
+chain of grants that ensure that everyone in the distribution has rights
+under the GPL\@.  In a mathematical sense, this bounds the bottom ---
+making sure that future licensees get no fewer rights than than the
+licensee before.
+
+The second sentence of \S 6 does the opposite; it bounds from the top.  It
+prohibits any licensor along the distribution chain from placing
+additional restrictions on the user.  In other words, no additional
+requirements may trump the rights and freedoms given by GPL\@.
+
+The final sentence of \S 6 makes it abundantly clear that no individual
+entity in the distribution chain is responsible for the compliance of any
+other.  This is particularly important for non-commercial users who have
+passed along a source offer under \S 3(c), as they cannot be assured that
+the issuer of the offer will honor their \S 3 obligations.
