You shouldn’t. Apple preserves backdoors in iCloud encryption to enable warrantless government surveillance. They have no other option.

It's weird to hang up on this specific item because they do actually offer an E2EE icloud option. Lose your key: lose your data.

		Nobody has it on, and unless BOTH sides are using it, your iMessage conversations are all readable by Apple, because they are backed up twice - one for each end. This option is also disabled in the UK - an intentionally preserved backdoor for government access. https://support.apple.com/en-gb/122234
