content: Doing that would violate the DMCA likely.  I do think there will soon be a market for open source devices with toggles for secure boot/DRM though. People are getting fed up with this shit, and will eventually hit a tipping point. Imagine: a tractor that comes with a secure boot loader, that is locked and mostly non hackable (like the tractors today), but also ships with the keys to unlock it and the source for the firmware.  For the warranty,you could put several non resettable fuses on various systems that blow if certain parameters are violated: you run the engine too hot? Permanent bit flipped. Run the mill too fast? Permanent bit flipped. Any bits flipped and your warranty on that part is void, but the rest could even still be covered.
