Developers who create open source software hold the copyright to their work but grant users a license, typically the GPL, to use and modify the software. However, users have obligations under these licenses, such as making any modified versions of the software freely available. Some companies download and use open source software without attending to their license obligations, risking legal issues. Stakeholders in open source software include developers, companies that use or develop software, programmers, and general users. Utilitarian and deontological analyses both support following open source licenses to maximize benefits and fulfill duties around intellectual property. Developers should give credit to original creators and make any modifications publicly available, while companies should verify that license terms are followed.
