 Hoarders may get piles of money,
 That is true, hackers, that is true.
 But they cannot help their neighbors;
 That's not good, hackers, that's not good.

 When we have enough free software
 At our call, hackers, at our call,
 We'll throw out those dirty licenses
 Ever more, hackers, ever more.

 Join us now and share the software;
 You'll be free, hackers, you'll be free.
