  Definition of "Free software"

  opensource gnu definition freeware free-software

  • o understand the concept, you should think of “free” as in “free speech,” not as in “free beer”.
  • Thus, “free software” is a matter of liberty, not price.

  • A program is free software if the program's users have the four essential freedoms: 

      
     
    • The freedom to run the program, for any purpose (freedom 0).
     
    • The freedom to study how the program works, and change it so it  does your computing as you wish (freedom 1). Access to the source  code is a precondition for this. 
     
    • The freedom to redistribute copies so you can help your neighbor  (freedom 2). 
     
    • The freedom to distribute copies of your modified versions  to others (freedom 3). By doing this you can give the whole  community a chance to benefit from your changes.  Access to the source code is a precondition for this.
  • either gratis or charging a fee for distribution,
  • Being free to do these things means (among other things) that you do not have to ask or pay for permission to do so.
  • In this freedom, it is the user's purpose that matters, not the developer's purpose; you as a user are free to run the program for your purposes, and if you distribute it to someone else, she is then free to run it for her purposes, but you are not entitled to impose your purposes on her.
  • Therefore, accessibility of source code is a necessary condition for free software

  • In the GNU project, we use  copyleft to protect these freedoms legally for everyone.
  • Sometimes government export control regulations and trade sanctions can constrain your freedom to distribute copies of programs internationally.
  • Most free software licenses are based on copyright
  • hat means there are many possible ways such a license could be unacceptably restrictive and nonfree.

  • Freedom 1 includes the freedom to use your changed version in place of the original. If the program is delivered in a product designed to run someone else's modified versions but refuse to run yours — a practice known as “tivoization” or (through blacklisting) as “secure boot” — freedom 1 becomes a theoretical fiction rather than a practical freedom. This is not sufficient. In other words, these binaries are not free software even if the source code they are compiled from is free.
  • In order for these freedoms to be real, they must be permanent and irrevocable as long as you do nothing wrong; if the developer of the software has the power to revoke the license, or retroactively change its terms, without your doing anything wrong to give cause, the software is not free.
  • For example, copyleft (very simply stated) is the rule that when redistributing the program, you cannot add restrictions to deny other people the central freedoms. This rule does not conflict with the central freedoms; rather it protects them.
  • Free software does not mean non-commercial. A free program must be available for commercial use, commercial development, and commercial distribution. Commercial development of free software is no longer unusual; such free commercial software is very important. You may have paid money to get copies of free software, or you may have obtained copies at no charge. But regardless of how you got your copies, you always have the freedom to copy and change the software, even to  sell copies.

  • The Free Software Definition

      

     We maintain this free software definition to show clearly what must be true about a particular software program for it to be considered free software. 

  • Free software is a matter of the users' freedom to run, copy, distribute, study, change and improve the software. More precisely, it refers to four kinds of freedom, for the users of the software: 

      
     
    • The freedom to run the program, for any purpose (freedom 0).
     
    • The freedom to study how the program works, and adapt it to  your needs (freedom 1). Access to the source code is a precondition  for this. 
     
    • The freedom to redistribute copies so you can help your neighbor  (freedom 2). 
     
    • The freedom to improve the program, and release your improvements  to the public, so that the whole community benefits (freedom 3).   Access to the source code is a precondition for this. 
     
      

     A program is free software if users have all of these freedoms.
