 purpose in doing so is to restore the users' legal rights that the technology
 wrongfully prevents them from exercising.
 % FIXME: Remove FSF specific parts
 As a digital rights organization, we would not be following our mission if we
 did not oppose these injustices.  But the reason our license must respond to
 these practices at all is the result of a remarkable irony. Those who wish to
 impose DRM on the public would like to do so by using software covered by the
 GPL, a license that is intended to preserve the very freedom that they seek
 to crush.  They are not satisfied merely with publishing programs having
 limited capability, which free software permits. They seek to go further, to
 prevent the user from removing those limits, turning Freedom 1, the freedom
 to modify, into a sham.
 GPLv2 did not address the use of technical measures to take back the rights
 that the GPL granted, because such measures did not exist in 1991, and would
 have been irrelevant to the forms in which software was then delivered to
 users.  But GPLv3 must address these issues: free software is ever more
 widely embedded in devices that impose technical limitations on the user's
 freedom to change it.
 These unjust measures must not be confused with legitimate applications that
 give users control, as by enabling them to choose higher levels of system or
 data security within their networks, or by allowing them to protect the
 security of their communications using keys they can generate or copy to
 other devices for sending or receiving messages.  These technologies present
 no obstacles to the freedom of free software. The user is presented with
 choices, and figuratively as well as literally retains all the keys to the
 digital home.
 By contrast, technical restrictions that allow other parties to control the
 user have no legitimate social purpose.  In existing applications where the
 user is not afforded the same degree of real power to modify the free
 software in his system that vendors or distributors have retained, or have
 conveyed to third parties, the software has been delivered in a fashion that
 violates the spirit of the GPL, regardless of whether it complies with the
 letter of the license. The freedoms the GPL grants have actually been
 withdrawn by technical means.  It may even be a crime for the user to modify
 that free software to escape from those restrictions and regain control over
 what is still, at least nominally, his own system.
 % FIXME: reference \S6 and \S3 stuff.
 We believe that these provisions, taken together, are a minimalist set of
 terms sufficient to protect the free software community against the threat of
 invasive para-copyright.
 users.  GPLv3 addresses these issues, particularly because copylefted
 software is ever more widely embedded in devices that impose technical
 limitations on the user's freedom to change it.
 However, FSF always made a clear distinction to avoid conflating these
 ``lock-down'' measures with legitimate applications that give users control,
 as by enabling them to choose higher levels of system or data security within
 their networks, or by allowing them to protect the security of their
 communications using keys they can generate or copy to other devices for
 sending or receiving messages.  Such technologies present no obstacles to
 software freedom and the goals of copyleft.
 The public GPLv3 drafting process sought to balance these positions of
 copyleft advocates with various desperate views of the larger
 Free-Software-using community.  Ultimately, FSF compromised to the GPLv3\S3
 and GPLv3\S6 provisions that, taken together, are a minimalist set of terms
 sufficient to protect the software freedom against the threat of invasive
 para-copyright.
 The compromises made were ultimately quite reasonable.  The primary one is
 embodied in GPLv3\S6's ``User Product'' definition (see \S~\ref{user-product}
 in this tutorial for details).  Additionally, some readers of early GPLv3
 drafts seem to have assumed GPLv3 contained a blanket prohibition on DRM; but
 it does not.  In fact, no part of GPLv3 forbids DRM regarding non-GPL'd
 works; rather, GPLv3 forbids the use of DRM specifically to lock-down
 restrictions on users' ability to install modified versions of the GPL'd
 software itself, but again, \textit{only} with regard to User Products.
 Large enterprise users of free software often contract with non-employee
 developers, often working offsite, to make modifications intended for
