 \section{GPL \S 5: Acceptance, Copyright Style}
 \label{GPLs5}
 
+\S 5 brings us to perhaps the most fundamental misconception and common
+confusion about GPL\@.  Because of the prevalence of proprietary software,
+most users, programmers, and lawyers alike tend to be more familiar with
+EULAs.  EULAs are believed by their authors to be contracts, requiring
+formal agreement between the licensee and the software distributor to be
+valid.  This has led to mechanisms like ``shrink-wrap'' and ``click-wrap''
+as mechanisms to perform acceptance ceremonies with EULAs.
+
+The GPL does not need contract law to ``transfer rights''.  No rights are
+transfered between parties.  By contrast, the GPL is permission slip to
+undertake activities that would otherwise been prohibited by copyright law.
+As such, it needs no acceptance ceremony; the licensee is not even
+required to accept the license.
+
+However, without the GPL, the activities of copying, modifying and
+distributing the software would have otherwise been prohibited.  So, the
+GPL says that you only accepted the license by undertaking activities that
+you would have otherwise been prohibited without your license under GPL\@.
+This is a certainly subtle point, and requires a mindset quite different
+from the contractual approach taken by EULA authors.
+
+An interesting side benefit to \S 5 is that the bulk of users of Free
+Software are not required to accept the license.  Undertaking fair and
+unregulated use of the work, for example, does not bind you to the GPL,
+since you are not engaging in activity that is otherwise controlled by
+copyright law.  Only when you engage in those activities that might have an
+impact on the freedom of others does license acceptance occur and the
+terms begin to bind you to fair and equitable sharing of the software.  In
+other words, the GPL only kicks in when it needs to for the sake of
+freedom.

 Under copyright law, the GPL has granted various rights and freedoms to
 the licensee to perform acts of copying, modification, and redistribution
 that would otherwise have been prohibited by default.  Since, barring
 special permission from the copyright holder, the GPL is a licensee's one
 and only license to the software (thanks to \S 6),
