Why is the Eclipse Public License used to license most of the content made available by the Eclipse Foundation?
The terms and conditions of the EPL were found to be most appropriate for the Eclipse Foundation. Software made available by the Eclipse Foundation is used by developers who want to freely plug into and extend or alter the content. The EPL goes to great lengths to support and encourage the collaborative open source development of the content, while maximizing the ability to use and/or integrate the content with software licensed under other licenses, including many commercial licenses. Since the Eclipse Foundation seeks to encourage developers of both open source and proprietary development tools to embrace the content, this flexibility is critical.
