But regardless of how you got your copies, you always have the freedom to copy and change the software, even to sell copies.

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.

Rules about how to package a modified version are acceptable, if they don t substantively block your freedom to release modified versions, or your freedom to make and use modified versions privately. Rules that if you make your version available in this way, you must make it available in that way also can be acceptable too, on the same condition. (Note that such a rule still leaves you the choice of whether to publish your version at all.

) Rules that require release of source code to the users for versions that you put into public use are also acceptable. It is also acceptable for the license to require that, if you have distributed a modified version and a previous developer asks for a copy of it, you must send one, or that you identify yourself on your modifications. In the GNU project, we use copyleft to protect these freedoms legally for everyone.

But non-copylefted free software also exists. We believe there are important reasons why it is better to use copyleft, but if your program is non-copylefted free software, we can still use it. See Categories of Free Software for a description of how free software, copylefted software and other categories of software relate to each other.

Sometimes government export control regulations and trade sanctions can constrain your freedom to distribute copies of programs internationally. Software developers do not have the power to 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 jurisdictions of these governments.

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 (though this does happen occasionally). However, some free software licenses are based on contracts, and contracts can impose a much larger range of possible restrictions.

That means there are many possible ways such a license could be unacceptably restrictive and non-free. We can t possibly list all the ways that might happen. If a contract-based license restricts the user in an unusual way that copyright-based licenses cannot, and which isn t mentioned here as legitimate, we will have to think about it, and we will probably conclude it is non-free.

When talking about free software, it is best to avoid using terms like give away or for free , because those terms imply that the issue is about price, not freedom. Some common terms such as piracy embody opinions we hope you won t endorse. See Confusing Words and Phrases that are Worth Avoiding for a discussion of these terms.

We also have a list of translations of free software into various languages.. 1132 Appendix D The Free Software Definition Finally, no .net vs 2010 EAN 13 te that criteria such as those stated in this free software definition require careful thought for their interpretation. To decide whether a specific software license qualifies as a free software license, we judge it based on these criteria to determine whether it fits their spirit as well as the precise words.

If a license includes unconscionable restrictions, we reject it, even if we did not anticipate the issue in these criteria. Sometimes a license requirement raises an issue that calls for extensive thought, including discussions with a lawyer, before we can decide if the requirement is acceptable. When we reach a conclusion about a new issue, we often update these criteria to make it easier to see why certain licenses do or don t qualify.

If you are interested in whether a specific license qualifies as a free software license, see our list of licenses. If the license you are concerned with is not listed there, you can ask us about it by sending us email at

If you are contemplating writing a new license, please contact the FSF by writing to that address. The proliferation of different free software licenses means increased work for users in understanding the licenses; we may be able to help you find an existing Free Software license that meets your needs. If that isn t possible, if you really need a new license, with our help you can ensure that the license really is a Free Software license and avoid various practical problems.

______________________________________________________________________ Another group has started using the term open source to mean something close (but not identical) to free software . We prefer the term free software because, once you have heard it refers to freedom rather than price, it calls to mind freedom. The word open never does that.
