To be clear: Motorola hardware isn’t open-source hardware. GrapheneOS is the most hardened Android you can run today, but it still depends on vendor hardware stacks and the Android framework. Linux-native phones move in a different direction—open operating systems and open hardware control—mainline kernels, open stacks, repairable and user-serviceable hardware, and devices with physical radio kill switches. That kind of architecture has a very different long-term ceiling for open-source privacy and security development.
