I really do not understand why people using nostr or Bitcoin because of its morals, would use happily an iphone... Apple does not care about you and has a really bad track record even involving the chinese government.

They are also locked down and you are at complete mercy of apples intentions.

stop overpaying and using their devices for your daily data traffic!

No, iphones are not more secure in situations where you want to protect data. If you dont want hackers to access data, why would apple be okay?
