When I see such hardware, I directly go to see if it provides its sources. It does: https://github.com/ROCKNIX/distribution

Just a reminder that those funky hardwares are full of open source software builds (often emulators) and often does not follow the GPL licence licence and providing source code back. Things are moving in the good direction but I thinks its important for us, as user, to complain about GPL licence, specifically for such hardware that often needs updates.

This one seems pretty serious.
