Seems by and large reasonable but notably doesn't address the elephant in the room: potential their hardware has built-in backdoors for China government access. Should be simple enough to provide at least basic assurances (a la Apple)
Backdoors come in red, white, and blue colors too besides just red and yellow. This isn't just whataboutism, as wannacry and the like show. We have no more accountability here or there. Traffic can be encrypted end to end anyway. Paranoia can be counter productive. If 5g became worthless during a military confrontation with china there are many other choices for emergency communication. Even mentioning this has me worried with a loose cannon in the executive.
