Proof: go into settings and disable every tracking options, and then capture traffic from the device through a router with openwrt running tcpdump or wireshark on a computer with a bridge setup with ip forwarding and iptables rule.
Did this experiment already twice to prove to people that Apple device do phone home plenty. Then I repeat the same experiment with my rooted android phone running a custom rom, and people watch the sparse wireshark trace with the only packets being sent are dns then ntp to the android ntp server.
What data are you claiming Apple is sending ?
Doesn’t Apple ask you whether you want to enable this when you set up the device?
They also ask during setup and regularly after major updates. I know because I refuse every time. Also, quite often it is opt in, with the box to send information unticked by default.
Anyone can repeat this experiment at home with a laptop and 2 usb to ethernet adaptors.
