Approximately nobody has turned on advanced data protection.
When you go to an Apple store and buy and use an iPhone, as millions do, you are prompted to create an Apple Account and log in. iCloud and iCloud Backup are automatically and silently enabled. The device automatically runs non-e2ee backups nightly.
This is how almost every iPhone on Earth runs. Most people don’t even know the feature exists. Even amongst techies that know about it, almost nobody has it enabled.
The real practical reason for that is that that even techies know the risks of being wholly responsible for your encryption keys and most are comfortable with the current tradeoff. I have a couple more security minded friends who simply disable iCloud backups and make encrypted backups locally, which was available before ADP.
