> iMessage and Whatsapp are both this. Since you only need one participant in a conversation to not enable backup encryption, I would guess that law enforcement has cleartext access to over 99% of messages sent by americans. I'd guess less only because Apple is so stingy on iCloud storage. A majority of iOS users I know don't have iMessage backup enabled because they're not willing to pay for additional iCloud storage.
