The reason why I trust Apple a little bit more than, say, Google on something like this is that Apple is pitching their products as luxury goods - a way to be different from the hoi polloi - so they need features to plausibly differentiate along these lines. And privacy is one thing that they know Google will never be able to offer, given its business model, so it makes perfect sense for Apple to double down on that.

(Ironically, this means that Apple users benefit from Android being the dominant platform.)
