It's my understanding that you cannot really defend against backdoors. You can somewhat mitigate their impact through good security/privacy design. Your energies may be better invested in a position that assumes any and all of the radios have been compromised or exploited and work from there (this is what mainstream flagship smartphone SoC/OS designers already do).
The entities that are putting in backdoors don't respect the law, and obviously will do what they can to obfuscate the backdoor enough to pass regulatory reviews.
My threat model is precisely entities that don't respect law or are unethical. So, the question then boils down to whether current regulatory review processes can catch such backdoors and the people running these processes cannot be bribed or otherwise forced to skip proper review?
