Sorry, but I'm afraid your assertion is wrong. Replicant doesn't use any closed binary blobs. There's no magic involved. It "replaces or avoids every proprietary component of the system, such as user-space programs and libraries as well as firmwares". In other words, not everything may work but it is entirely free/open and is the only mobile operating approved by the FSF. Replicant developers have also contributed mainline Linux and U-Boot support for devices such as the LG Optimus Black and the Amazon Kindle Fire (1st gen).
