Editing Source-available software (section)

== Distinction from free and open-source software ==
Any software is ''source-available'' in the broad sense as long as its source code is distributed along with it, even if the user has no legal rights to use, share, modify or even [[compile]] it. It is possible for a software to be both source-available software and [[proprietary software]] (e.g. [[id Software]]'s ''[[Doom (1993 video game)|Doom]]'').

In contrast, the definitions of free software and open-source software are much narrower. [[Free software]] and/or [[open-source software]] is also always ''source-available software'', but not all source-available software is also free software and/or open-source software. This is because the official definitions of those terms require considerable additional rights as to what the user can do with the available source (including, typically, the right to use said software, with attribution, in derived commercial products).<ref>{{cite web |title=The Open Source Definition {{!}} Open Source Initiative |url=https://opensource.org/osd |website=opensource.org}}</ref>

In the broad sense, any FOSS license is a ''source-available'' license. In the narrow sense,<ref name="dod"/> the term ''source-available'' specifically excludes FOSS software.
