Free and Open Source software is licensed to guarantee anybody rights to freely use, modify, and redistribute the software. If software is Free (as in Freedom) 🔗 or Open Source 🔗, it facilitates choice. The choice to use the software, the choice to learn the software, and the choice to join, share, and participate in a community - a community full of enthusiastic partners that want to see the software grow and succeed.
