The point was that he has no idea where the boundaries around between Apple and Google and what is within the realm of possibility of abuse and what is strictly impossible without him tapping "accept" via a system prompt. It is not possible for Google to track his location without him granting permission to do so on his iPhone. It is not possible to get precise location data without a prompt and a blue system indicator. It is not possible to get repeated location data without iOS eventually notifying you of the background activity (even the stock Weather app is not immune to this). All of this is because Apple has fine control over the system.
