\chapter{ThinkPenguin Wireless Router: Excellent CCS}

Too often, case studies examine failure and mistakes.  Indeed, most of the

chapters that follow herein will consider the myriad difficulties discovered

in community-oriented GPL enforcement for the last two decades.  However, to

begin, we offer a study in how copyleft compliance done correctly.

This example is, in fact, more than ten years in the making.  Since almost

the inception of for-profit corporate adoption of Free Software, companies

have requested a clear example of a model citizen to emulate.  Sadly, while

community-oriented enforcers have vetted uncounted thousands of CCS

candidates from hundreds of companies, the CCS release describes the first

one CCS experts have declared a  ``pristine example''.

Of course, most CCS examined for the last decade has (eventually) complied

with the GPL, perhaps after many iterations of review by the enforcer.

However, in the experience of the two primary community-oriented enforcers,

Conservancy and the FSF, such CCS results routinely fix the description of

``barely complies with GPL's requirements''.  To use an academic analogy:

while a ``C'' is certainly a passing grade, any instructor prefers to

disseminate to the class a exemplar sample that earned an ``A''.

Fortunately, thanks in large part to the industry pressure of the FSF's

``Respects Your Freedom'' (RYF) certification campaign\footnote{\href{RYF is

    a campaign by FSF to certify products that truly meet the principles of

    software freedom}.  Products must meet

  \href{http://www.fsf.org/resources/hw/endorsement/criteria}{strict

    standards for RYF certification}, and among them is a pristine example of

  CCS\@}, electronics products have begun to appear on the market that are

held to a higher standard of copyleft compliance.  As such, for the first

time in the history of copyleft, CCS experts have pristine examples to study

and present as exemplars worthy of emulation.

This case study therefore examines the entire life-cycle of a GPL compliance

investigation: from product purchase, to source request, to CCS review.
