This coupled along with the fact that iMessage's E2EE has been backdoored by the non-E2EE iCloud Backup key escrow is a good argument for leaving iMessage, FaceTime, and iCloud all turned off on a device. I go one step further and leave the SIM card out, which means the SMS vulnerability path is closed too. |
So in either case... turn off native messaging and use Signal or something if you are paranoid. You aren't really using the "phone" part anymore, so buy an iPod touch or something.
Also, iMessage is fully E2E if you disable iCloud Backup. Which can easily do in Settings.
