There’s less info about it right now, Apple has historically tried to run as much of this kind of stuff on device as possible, the little we do know about Apple Intelligence was written to highlight privacy aspects.
Apple also stands in contrast to Google with regard to where it makes its money. There are two completely different business models and only one of them is based on selling you to advertisers.
Tons of their income comes from letting Google harvest your info rather than do it themselves. Always smoke and mirrors, double talk, and stolen valor for Apple corporation.
I heavily use both platforms, whatever I talk about or wherever I go, I see targeted ads. When I speak about brand X, I immediately see ads for it both in ios and android. Plus every device mic is being listened to all the time, advertising agencies are your proof. Sure android devices collect more data in practice, however the data that’s not being collected by ios can be inferred from the data that’s already been collected. Do you really believe a company when they say their devices are made to ensure your privacy? Google literally says the same thing on their privacy policies ;) it’s all legal mumbo jumbo that doesn’t mean what it’s supposed to.
