100% agree with this. However, being presented with a user-selectable option would be ideal (i.e. more security vs. more convenience). You know, sort of like File Vault (Apple’s warning: “WARNING: Don’t forget your recovery key. If you turn on FileVault and then forget your login password and can’t reset it, and you also forget your recovery key, you won’t be able to log in, and your files and settings will be lost forever.”).For every person who would prefer end-to-end-encrypted backups, there's a person who would stand to lose their family photos for good, and would go to the Genius Bar and blame an Apple staffer.
