|
The free software definition presents the criteria for whether a |
19 |
|
particular software program qualifies as free software. From time to |
20 |
|
time we revise this definition, to clarify it or to resolve questions |
21 |
|
about subtle issues. See the <a href="#History">History section</a> |
22 |
|
below for a list of changes that affect the definition of free |
23 |

software. |

We maintain this free software definition to show clearly what must be |
“Free software” means software that respects users' |

freedom and community. Roughly, <b>the users have the freedom to run, |

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

Freedom 1 includes the freedom to use your changed version in place of |
127 |
|
the original. If the program is delivered in a product designed to |
128 |
|
run someone else's modified versions but refuse to run yours — a |
129 |
|
practice known as “tivoization” or “lockdown”, |
130 |
|
or (in its practitioners' perverse terminology) as “secure |
131 |
|
boot” — freedom 1 becomes a theoretical fiction rather |
132 |
|
than a practical freedom. This is not sufficient. In other words, |
133 |
|
these binaries are not free software even if the source code they are |
134 |

compiled from is free. |

However, rules about how to package a modified version are acceptable, |
190 |
|
if they don't substantively limit your freedom to release modified |
191 |
|
versions, or your freedom to make and use modified versions privately. |
192 |
|
Thus, it is acceptable for the license to require that you change the |
193 |
|
name of the modified version, remove a logo, or identify your |
194 |
|
modifications as yours. As long as these requirements are not so |
195 |
|
burdensome that they effectively hamper you from releasing your |

changes, they are acceptable; you're already making other changes to |

|
A special issue arises when a license requires changing the name by |
214 |
|
which the program will be invoked from other programs. That |
215 |
|
effectively hampers you from releasing your changed version so that it |
216 |
|
can replace the original when invoked by those other programs. This |
217 |
|
sort of requirement is acceptable only if there's a suitable aliasing |
218 |
|
facility that allows you to specify the original program's name as an |
219 |
|
alias for the modified version.</p> |
