Software Freedom Conservancy

According to our Principles, we always begin discussions with GPL violators privately. Many of these discussions are ongoing at any time. Recently, we received many questions about GPLv2's requirements regarding installation of modified versions of GPLv2'd software on the device on which the software was distributed. GPLv2 was drafted in anticipation of future uses of the software, and includes specific license text regarding installation:

Unfortunately, we find that GPL violators often ignore (sometimes inadvertently) this part of that license text, which has always been of great importance: “the scripts used to control … installation of the executable”.

When a system is 100% FOSS “by design”, meeting this requirement is easy. We applaud the many community-oriented commercial projects that build their own hardware and give their users complete software freedom, such as the LulzBot Mini 3D Printer. We wish that all companies would follow that example and grant customers universal software freedom. Unfortunately, that is currently not realistic, even in the medium term.

Copyleft advocates have always contemplated that some companies will choose to ship proprietary software on the same device as the GPL'd works. Indeed, GPLv2 foresaw this possibility and permits that “mere aggregation” — as long as compliance is achieved for the GPLv2-covered works included on the device.
