“Free software” is a matter of liberty, not price. To understand |

Free software is a matter of the users' freedom to run, copy, distribute, |

study, change and improve the software. More precisely, it means that the |

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

54 |

things means (among other things) that you do not have to ask or pay |

The freedom to run the program means the freedom for any kind of person |

overall job and purpose, without being required to communicate about it |

71 |

|
the <em>user's</em> purpose that matters, not the <em>developer's</em> |
72 |
rms |

purpose; you as a user are free to run the program for your purposes, |
73 |

The freedom to redistribute copies must include binary or executable |

forms of the program, as well as source code, for both modified and |
80 |

1.48 |
unmodified versions. (Distributing programs in runnable form is necessary |
81 |
rms |
1.88 |
for conveniently installable free operating systems.) It is OK if there |
82 |
sinuhe |
1.48 |
is no way to produce a binary or executable form for a certain program |
83 |
|
|
(since some languages don't support that feature), but you must have the |
84 |

freedom to redistribute such forms should you find or develop a way to |

make them. |

In order for freedoms 1 and 3 (the freedom to make changes and the |
90 |
|
|
freedom to publish improved versions) to be meaningful, you must have |
91 |
|
|
access to the source code of the program. Therefore, accessibility of |
92 |
rms |
1.92 |
source code is a necessary condition for free software. Obfuscated |
93 |
|
|
“source code” is not real source code and does not count |
94 |
|
|
as source code. |

Freedom 1 includes the freedom to use your changed version in place of |
99 |

the original. If the program is delivered in a product designed to |
100 |

run someone else's modified versions but refuse to run yours — |
101 |
rms |
1.80 |
a practice known as “tivoization” or (through |
102 |
lajjr3 |
1.85 |
blacklisting) as “secure boot” — freedom 1 becomes a |
103 |
rms |
1.80 |
theoretical fiction rather than a practical freedom. This is not |
104 |
rms |
1.86 |
sufficient. In other words, these binaries are not free software |
105 |

even if the source code they are compiled from is free. |

One important way to modify a program is by merging in available free |
110 |
|
|
subroutines and modules. If the program's license says that you |
111 |
rms |
1.88 |
cannot merge in a suitably licensed existing module — for instance, if it |
112 |
|
|
requires you to be the copyright holder of any code you add — then the |
113 |
rms |
1.74 |
license is too restrictive to qualify as free. |

Freedom 3 includes the freedom to release your modified versions |
118 |
rms |
1.89 |
as free software. A free license may also permit other ways of |
119 |
|
|
releasing them; in other words, it does not have to be |
120 |
|
|
a <a href="/copyleft/copyleft.html">copyleft</a> license. However, a |
121 |
|
|
license that requires modified versions to be nonfree does not qualify |
122 |
|
|
as a free license. |

In order for these freedoms to be real, they must be permanent and |
127 |
|
|
irrevocable as long as you do nothing wrong; if the developer of the |
128 |
|
|
software has the power to revoke the license, or retroactively change |
129 |
|
|
its terms, without your doing anything wrong to give cause, the |
130 |

software is not free. |

However, certain kinds of rules about the manner of distributing free |
135 |
|
|
software are acceptable, when they don't conflict with the central |
136 |
|
|
freedoms. For example, copyleft (very simply stated) is the rule that |
137 |
|
|
when redistributing the program, you cannot add restrictions to deny |
138 |
|
|
other people the central freedoms. This rule does not conflict with |
139 |

the central freedoms; rather it protects them. |

“Free software” does not mean “noncommercial.” A free |
144 |
rms |
1.75 |
program must be available for commercial use, commercial development, |
145 |

and commercial distribution. Commercial development of free software |
146 |

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 |
148 |
|
|
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 |

Whether a change constitutes an improvement is a subjective matter. |
155 |
|

If your modifications are limited, in substance, to changes that |
156 |

However, rules about how to package a modified version are acceptable, if they |
161 |
|
|
don't substantively limit your freedom to release modified versions, or |
162 |
karl |
1.91 |
your freedom to make and use modified versions privately. Rules that “if |
163 |
sinuhe |
1.48 |
you make your version available in this way, you must make it available in |

165 |
sinuhe |
1.48 |
such a rule still leaves you the choice of whether to publish your version |
166 |
|
|
at all.) Rules that require release of source code to the users for |
167 |
|
|
versions that you put into public use are also acceptable. It is also |
168 |
rms |
1.88 |
acceptable for the license to require that you identify |
169 |
|
|
your modifications as yours, or that, if you have distributed a modified |
170 |
|
|
version and a previous developer asks for a copy of it, you must send |
171 |

one. |

Sometimes government <a id="exportcontrol">export control regulations</a> |

eliminate or override these restrictions, but what they can and must do |

is refuse to impose them as conditions of use of the program. In this |

way, the restrictions will not affect activities and people outside the |

Most free software licenses are based on copyright, and there are limits |

on what kinds of requirements can be imposed through copyright. If a |

copyright-based license respects freedom in the ways described above, it |

is unlikely to have some other sort of problem that we never anticipated |

licenses are based on contracts, and contracts can impose a much larger |

When talking about free software, it is best to avoid using terms |

like “give away” or “for free,” because those terms imply that |

Finally, note that criteria such as those stated in this free software |
235 |
sinuhe |
1.48 |
definition require careful thought for their interpretation. To decide |
236 |
|
|
whether a specific software license qualifies as a free software license, |
237 |
|
|
we judge it based on these criteria to determine whether it fits their |
238 |
|
|
spirit as well as the precise words. If a license includes unconscionable |
239 |
|
|
restrictions, we reject it, even if we did not anticipate the issue |
240 |
|
|
in these criteria. Sometimes a license requirement raises an issue |
241 |
|
|
that calls for extensive thought, including discussions with a lawyer, |
242 |
|
|
before we can decide if the requirement is acceptable. When we reach |
243 |
|
|
a conclusion about a new issue, we often update these criteria to make |
244 |
|
|
it easier to see why certain licenses do or don't qualify. |

Any kind of work <em>can</em> be free, and the definition of free software |
287 |
|
|
has been extended to a definition of <a href="http://freedomdefined.org/"> |
288 |
|
|
free cultural works</a> applicable to any kind of works. |

Another group has started using the term “open source” to mean |
295 |
|
|
something close (but not identical) to “free software.” We |
296 |
|
|
prefer the term “free software” because, once you have heard that |
297 |
yavor |
1.61 |
it refers to freedom rather than price, it calls to mind freedom. The |
298 |
karl |
1.91 |
word “open” <a href="/philosophy/open-source-misses-the-point.html"> |
299 |
yavor |
1.61 |
never refers to freedom</a>. |
