iPhone involves a lot of telemetry which Apple sends it to itself. We don’t know what kind of contract Apple has with Qualcomm but if it involves Apple anonymising and sending the data to Qualcomm for using its chips then it’s likely going to be the same just in a different form. I’m pretty sure Qualcomm would like some kind of telemetry from its partners it sells chips to.

That's actually not likely at all. There's no reason for Apple to trash its reputation by doing something stupid like this for Qualcomm's benefit.

The iPhone has plenty of it's own telemetry like OCSP and Find My. No need to play cats vs dogs here.

Telemetry is something like : this is the history of modem signals etc. Something Qualcomm might have in its contract.
