There's a good chance this is where the interoperability comes into play. They might not be able to track direct communications but people will still interact with public content on places such as Instagram. As soon as accounts are linked they'll be able to advertise in places such as WhatsApp based on likes in Instagram.
I'm hoping this is a common enough printer that parts shouldn't be too hard to find in the future. From what I can tell everything is fairly accessible for fixing. Thanks for the heads up though!
