I’m with them this time. 
Technically you don’t own them despite you payed for the hardware 
Well, guess their is no need anymore for that really as most likely more operating systems than only iOS probably suck data like that already by default and might share them for the right incentiv too. 
Mobile Handset Privacy: Measuring The Data iOS and Android Send to Apple And Google
Abstract — We investigate what data iOS on an iPhone shares
with Apple and what data Google Android on a Pixel phone
shares with Google. We find that even when minimally configured
and the handset is idle both iOS and Google Android share
data with Apple/Google on average every 4.5 mins. The phone
IMEI, hardware serial number, SIM serial number and IMSI,
handset phone number etc are shared with Apple and Google.
Both iOS and Google Android transmit telemetry, despite the
user explicitly opting out of this. When a SIM is inserted both
iOS and Google Android send details to Apple/Google. iOS sends
the MAC addresses of nearby devices, e.g. other handsets and
the home gateway, to Apple together with their GPS location.
Users have no opt out from this and currently there are few, if
any, realistic options for preventing this data sharing.
