Not sure, how active development is right now, but EdgeOS got forked from an open source devian based distro after that went commercial.
But EdgeOS was not the only fork, another one was VyOS (vyos.io). Pretty sure, that EdgeOS has done larger steps forward, especially, since it was bound to the hardware's developer.
