I first read "The Hacker's Manifesto" in _Thrasher_ magazine.
The original was published in Phrack Magazine in 1986.
The Thrasher version below is slightly modified from the original.
  Another one got caught today, it's all over the papers.
Teenager Arrested after Bank Tampering...
  Damn kids.  They're all alike.
  But did you, in your three-piece psychology and 1950's
lowbrow brain, ever take a look behind the eyes of a
hacker?  Did you ever wonder what made him tick, what
forces shaped him, what may have molded him?
  I am a hacker, enter my world... Mine is a world that
begins with school... I'm smarter than most of the other
kids.  This crap they teach us bores me...
  Damn underachiever.  They're all alike.
  I'm in junior high or high school.  I've listened to
teachers explain for the fifteenth time how to reduce
a fraction.  I understand it.  No, Ms. Smith, I didn't
show my work.  I did it in my head...
  Damn kid.  Probably copied it.  They're all alike.
  I made a discovery today.  I found a computer.  Wait
second, this is cool.  It does what I want it to.  If
it makes a mistake, it's because I screwed it up, not
because it doesn't like me.
  Or feels threatened by me...
  Or thinks I'm a smart ass...
  Or doesn't like teaching and shouldn't be here...
  Damn kid.  All he does is play games.  They're all
alike.
  And then it happens... a door opens to a world...
rushing through the phone line like heroin through an
addict's veins, an electronic pulse is sent out, a refuge
from the day-to-day incompetencies is sought... a board
is found.
  This is it... this is where I belong...  I know
everyone here... even if I've never met them, never
talked to them, may never hear from them again...  I
know you all.
  Damn kid.  Tying up the phone line again.  They're
all alike.
  You bet your ass we're all alike... we've been
spoon-fed baby food at school when we hungered for
steak... the bits of meat you did let slip through
were pre-chewed and tasteless.  We've been dominated
by sadists or ignored by the apathetic.  The few that
had something to teach found us willing pupils, but
those few are like drops of water in the desert.
  This is our world now... the world of the electron
and the switch, the silicon jungle.  We make use of an
already existing service without paying for what could
be dirt cheap if it wasn't run by profiteering gluttons,
and you call us criminals.  We explore and you call us
criminals.  We seek knowledge and you call us criminals.
We exist without skin color, without nationality, 
without religious bias... and you call us criminals.
You build atomic bombs, you wage wars, you murder,
cheat, and lie to us and try to make us believe it's
for our own good, yet we're the criminals.
  Yes, I am a criminal.  My crime is that of curiosity.
My crime is that of judging people by what they say and
think, not what they look like.  My crime is that of
outsmarting you, something that you will never forgive
me for.
  I am a hacker, and this is my manifesto.  You may stop
this individual, but you can't stop us all... after
all, we're all alike.
