Fair enough, though this is probably useful people for most non tech people, who might forget their passwords / lose keys, and don’t want to lose all access and data.

Personally, a few months ago I enabled Advanced Data Protection (ADP) which afaik does make iCloud backups (including messages), Photos, iCloud Drive and few other things inaccessible to Apple.

Whether you trust that Apple actually did throw away their keys after enabling the feature is a different story, but it’s good enough for me.

When enabling ADP there’s multiple warnings about how you’ll end up completely locked out if you lose all your devices / lose recovery keys / lose all hardware authenticators. Iirc I was also forced to register at least 2 yubikeys. For anyone tech savvy you should enable ADP.
