Apple will obey government orders to give data they have and can access.
No government order short of targeting a specific backdoored update to a specific person will allow them to give data they can't access.
And if you're doing something that can make a TLA force Apple to create a targeted iOS update just for you, it's not something regular people can or should worry about.
Apple keeps normal people safe from mass surveillance, being protected from CIA/NSA required going Full Snowden and it's not a technological problem, you need to change the way you live.
Do you not remember Edward Snowden? Eg this sort of info:
> The scandal broke in early June 2013, external when the Guardian newspaper reported that the US National Security Agency (NSA) was collecting the telephone records of tens of millions of Americans.
> The paper published the secret court order directing telecommunications company Verizon to hand over all its telephone data to the NSA on an "ongoing daily basis".
