They've redefined privacy to be privacy from everyone except themselves, and then indoctrinated people that they are the most privacy conscious company.
I have used Android and even tried to switch to Android a few years ago, but whenever I use Android, I can't shake the feeling that uncle Google watches whatever I do, I don't get the same feeling when I use iOS.
Weather either feeling is accurate I can't say, but I hesitate to trust an ad compny's OS over a computer company's OS.
Again, that is just a feeling, I make no claim wither way which is factually better.
iPhones tend to send close to the same types of info back home. When started, idle, inserting a SIM, on the settings screen, even when not logged in. Like, its very similar even when you look at comprehensive lists which a lot of people either don't know or ignore. I'm not saying that there aren't specific benefits or reasons to feel more comfortable with Apple. But saying its because they intrinsically are more private, I feel like that's a bridge too far
