GNU General Public License v3.0

                    GNU GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

                            Preamble

  The GNU General Public License is a free, copyleft license for
software and other kinds of works.

  The licenses for most software and other practical works are designed
to take away your freedom to share and change the works.  By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.  We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors.  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.

  To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights.  Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.

The preamble above is excerpted for reference. The complete license terms, including all 18 sections covering definitions, source code requirements, copyleft obligations, patent protections, and termination conditions, are incorporated by reference from the FSF’s canonical copy.

What this means

The GPL-3.0 is a copyleft license that requires anyone who distributes GPL-licensed code — or derivative works based on it — to make the complete source code available under the same license. Key provisions include:

Freedom to use: Run the software for any purpose
Freedom to study: Access and modify source code
Freedom to share: Distribute copies of the original
Freedom to improve: Distribute modified versions
Copyleft: Derivative works must carry the same GPL-3.0 license
Patent grant: Contributors grant patent rights for their contributions
Anti-Tivoization: Hardware restrictions that prevent users from running modified versions are prohibited

Which components use GPL-3.0

Components in the KBVE monorepo that incorporate GPL-3.0 licensed dependencies or are themselves released under GPL-3.0 include select game mods, tools, and plugins where the upstream dependency requires copyleft compliance. Each component’s Cargo.toml, package.json, or LICENSE file specifies its license. When a KBVE-authored component links against a GPL-3.0 library, the resulting binary is distributed under GPL-3.0 terms.

Interaction with the EULA

Proprietary KBVE applications covered by the EULA are distributed separately from GPL-3.0 components. Where a proprietary application incorporates a GPL-3.0 dependency, the relevant source code is made available as required by the license, and the EULA’s scope explicitly excludes those GPL-licensed portions.
