<blockquote>
(...) \[O\]ne day in 1984 Stallman 
received by mail a programming manual that had been borrowed
by American hacker and computer artist Don Hopkins. On the envelope
a stickers reading “Copyleft (L)” was used to seal the small package. 
Hopkins had bought a pack of stickers at a science fiction convention, where
hackers, including Stallman, often gathered and where it was common
for them to organise and share rooms, notably for “@” parties in which
people with email addresses could meet each other. 14 According to Hopkins, 
at that time the term copyleft was not part of the hacker culture, and
the stickers had been purchased in the dealer’s room of one convention
with other comics, political, and satirical stickers and buttons. 15 Knowing
Stallman’s appreciation for such things, Hopkins had decorated the letter
in a similar spirit. Little did he know that eventually the sticker and the
pseudo-copyright statement he had written as a joke (Figure 5.2), would
inspire Stallman to use the word copyleft to describe the properties of the
GPL. 16 This is how copyleft, the symbol of rebellious cultural practices,
ended up being claimed as a term to describe a particular mechanism of
free software licensing.
