If Apple really cared about iOS privacy they would give the user to ability to block any app from reaching the internet. A lot of the iOS apps I used have no need to ping the internet but they all do to gather metrics and do who-knows-what.
I use Little Snitch on the Mac and everything f**king program tries to connect to the internet. I block them all and only a handful fail so, yeah, they don't need to.
If Apple really cared about my privacy they would do this.
