50 -To address the problems with proprietary software, the FSF primarily promotes copyleft licenses, which require that any derivative works of the software be licensed under the same terms as the original code. The term "derivative work" is legally somewhat vague, but a common understanding is that it means a new work based on the original copyleft code that incorporates it at the source level. This ensures that when contributions are made to a copyleft project, or when copyleft code is directly reused in another project, the resulting work must be released under the same copyleft license. This prevents vendors from incorporating copyleft code into proprietary products, and ensures that any derivative works remain open source. In addition, copyleft licenses require that the source code be made available to users so that they can modify, build, and control the software themselves.

54 -The OSI aims to maximize the contributions and impact of open source by being open to all open source licenses. Permissive licenses have become very popular in recent years, especially in commercial contexts, but the OSI is open to choosing copyleft licenses if developers want to ensure that derivative works remain open and free. The FSF, on the other hand, tolerates all open source licenses, but has a strong preference for copyleft licenses, believing that all software should be protected in this way.
