@gruber About iMessage, isn’t it still that the iMessage traffic is merged on the same endpoint as the push notifications? So, if taking out iMessage all remote push notifications to iPhone would immediately cease to work.

This is how they shoehorned in iMessage under the nose of all phone operators, who already had been using the push notifications as one of the the major reasons for their customers to get a iPhone, and now they couldn’t block the iMessage traffic.

@gruber This is also why on flights, when you have ”messaging only” service, you are still getting the push notifications.

@magebarf I never thought about it, but with messaging-only service on airplane Wi-Fi, do you get all push notifications, not just those from messaging services?

@gruber Yet another reason why APNs cannot be blocked without causing a total shitstorm is because the Apple Business Manager platform and Apple's
MDM protocol relies on it for authenticating and communicating with devices. Without it, millions of company owned Apple devices would become cut off from their organizations.
