There is no privacy left. And to be honest, people worshipping their phones all day but complaining about privacy is the biggest WTF I have. This doesn't match.
Also I am a Mathematician and know statistics very well. The person, who is not on Facebook, but on WhatsApp, who works at X and lives in Y - we got you my friend.
You moved away? No problem! Someone photographed you casually, you weren't even the main character, we ignored you, and send it in a group chat you know nothing about. Well, we know all the others and can relate to anyway. And then? Well AI can very well predict you aging - easy. We have you already. Sleep well and dream of being unknown. Because... How do you know what you don't know?
I gave up on privacy because there is none anymore. Selling and publication of your data is a whole different story. And that's what Apple means by circumventing the rest.
