Free Software Foundation
We believe that freedom is an important end in itself — that software developers should respect the rights of users to share and modify the software they use. But the importance of freedom is made particularly evident by the first commercial Android phones. While most of the software running on the phones is free, and can be distributed by anyone, some components are proprietary. These components include several libraries and drivers necessary for interfacing with the phone’s hardware. Since these components are not free software, the user community cannot redistribute them. And since some of them are necessary to make the phone work, the user community can't share working firmwares.
