True, and once that one will be made open-source too, there's still the NSA tracking mobile phones worldwide and generating all kinds of privacy-invading data based on it:
The point made elsewhere in this thread is that even an open-source implementation can be exploited. If the baseband is tightly integrated, then that exploit gains the attacker full access.
From a security perspective, even a closed-source baseband could be ok as if it has proper separation from the rest of the system (though open-source would obviously be better).

(And until that is resolved, my mobile phone will stay in flight mode only.)
So once again, while tech may help in the short term, long-term solutions will have to be structural/systemic ones regarding government in general.
