> As requested, evidence of tracking in iPhones

That isn’t evidence of Apple tracking anything.

IDFA is used by Facebook and ad-tech companies.

Apple are switching IDFA to be Opt-In rather than opt out.

That’s what Facebook is complaining about.

The mechanism for tracking users is already present. What more proof do you need?

Even if you manage to toggle 3rd parties out of your phone. You cannot toggle the Apple out of it.

Evidence that Apple uses it.

The mechanism relies on libraries which send user behavior from other app to Facebook. These are correlated by the ID.

The identifier is not the mechanism. The mechanism is Facebook’s library.

Apple has no such mechanism.

> You cannot toggle the Apple out of it

False.

There is a toggle for the entire feature.
