I had never heard of the SFLC before, so this summary from their filing helped: "SFLC is a 501(c)(3) nonprofit legal services organization dedicated to protecting and advancing free software. SFLC provides pro bono legal representation to developers and educates the public about legal issues affecting free software development. SFLC represents a number of prominent developers and organizations that write and distribute free software directed at personal computing devices, including the Free Software Foundation, which develops and distributes GNU, a collection of free software operating system utilities; the Debian project, which distributes a complete free software operating system based on GNU and Linux; and the Foundation for Free Multimedia Technology, which develops free software commonly used for media playback." Overall this seems to clarify the legal distinction of installing a legally-obtained OS on all electronic devices you own. Jailbreaking of mobile phones was ruled legal in 2009--but that only covers a small subset of electronics which are becoming increasingly locked down.
