FY 2011 Annual Report
We're software roadies. Software Freedom Conservancy is a public charity that acts as a non-profit home for dozens of Free, Libre, and Open Source Software (FLOSS) projects. Conservancy©s charitable mission is to help improve, develop, and defend FLOSS, and we do that by providing business, legal, and administrative services to our member projects. We have the honor of working with member projects comprised of, in our humble opinion, many of the best software developers in the world. Some of our member projects develop system software so ubiquitous that it permeates virtually every part of our society©s electronics-driven lifestyle. Other member projects are redefining how software will be written and even how computer science will be taught to the next generation of developers. Still others find their niche by solving a small-but- persistent problem better than anyone else ± and attract a cult following of users because of it. And, best of all, all of our member projects release their software under a license that allows the public to study, use, improve, and share the source code. Conservancy provides all of our ªrock starº member projects with a comprehensive suite of services, and then we get out of their way to let them do what they do best: write great software for the public©s benefit. Our structure. Conservancy acts as a fiscal sponsor to our member projects. We©ve engaged the leadership of each member project©s developer community and executed a fiscal sponsorship agreement that allows us to adopt that project as an official part of Conservancy©s corporate structure. -
