Trying to fight with iMessage is a fool's errand. If you really are concerned about your mother or other family being able receive messages from you then maintain a private cicd server to continuously build GrapheneOS and hand your family members a device pre-configured where plain phone/SMS* are completely disabled with the one messaging app be it Element or SimpleX to be used. What you do is hand them the device and say "use this if you want to reach me". Give them a Yubikey to add to their keychain for disk encryption/decryption on the device. Give them a piece of paper with a six-digit PIN on it and ask them every hour throughout the two days you see them for the holidays what the PIN is. >> "but I shouldn't have to do all this" "Everything that we know and love is reducible to the absurd acts of chemicals, and there is therefore no intrinsic value in this material universe". Hypocrite that you are, for you trust the chemicals in your brain to tell you they are chemicals. All knowledge is ultimately based on that which we cannot prove. Will you fight? or will you perish like a dog? [*] 911 calls still enabled, also note that 911 works without a SIM card.
