Unsubscribing procedure seems however pretty acceptable > Messages in iCloud also uses end-to-end encryption. If you have iCloud Backup turned on, your backup includes a copy of the key protecting your Messages. This ensures you can recover your Messages if you lose access to iCloud Keychain and your trusted devices. When you turn off iCloud Backup, a new key is generated on your device to protect future messages and isn't stored by Apple. But wait does it mean that if you haven't iCloud backup activated but use local backup you can actually sync message without storing private key... the wording here is important would be nice if someone clarify.
