OK, that's a valid point and it's good to bring that up. I think we are now in the territory where this happens with all smart phones to one degree or another, no? So this gets into a larger question about privacy and phones.
Agreed. So, some random thoughts:
Personally, I have no problem with a phone collecting cell and wifi data anonymously. It helps everyone, including me. But that means there must be zero trail left. No unencrypted local files, etc.

Another mysterious item is that both Apple and Google issue a 12 or 24 hour temporary id to phones that are sending up data. After a little thought, I suspect that's so they'll know if someone out there is trying to game the system and stuff bogus info into Apple's location database. So, okay, but it's interesting.

I also want to be able to control my battery usage. When I choose to use a location app, I know I could be using more power, but that's my decision. (It's the same with widgets. It's my decision to allocate power as I wish.)
When the phone maker does things in the background without telling me or allowing me to opt out, then I've lost some control that I could and should have. So I should be able to turn off Apple's extra collection sequences.
