Philosophy: Software Freedom

  • The freedom to run the program, for any purpose
  • The freedom to study how the program works, and adapt it to your needs (access to the source code is a precondition for this)
  • The freedom to redistribute copies so you can help your neighbour
  • The freedom to improve the program, and release your improvements to the public, so that the whole community benefits. Access to the source code is a precondition for this
  • Free software saves money - it is free with no licences
  • It is easy to use
  • Can be run on laptops, servers and new and old computers
  • Gnu the Gnu and Tux the Penguin are the cute mascots
“It's Free Software and it gives you freedom!”


  • Free as in free speech and free chocolate
