iCloud Backup, on by default, is not end to end encrypted and uploads almost the entire contents of your device to Apple’s servers every night in a format they can read (effectively unencrypted). This includes your entire message history over SMS and iMessage and all attachments thereto.
It is safe to assume that the data collected and assembled by these daemons is part of the iCloud Backup, which you never have to explicitly enable; it happens when you log in to iCloud on the device, usually within minutes of first powering it on for most people.
> It is safe to assume
No need to assume anything. This data is not included in iCloud backup. That detail is included in the article.You are misinformed (or speculating) and spreading FUD.
>it should be opt-in
And definitely not "cannot even turn this shit off" mode.

I just recently installed Microsoft Office 2011 on my 27" iMac (2009 i5), and it absolutely shocked me that the default "Send User Data to Microsoft" option was `OPT-OUT`, requiring the user to manually click a radio-button to `OPT-IN` to usage data collection.
This was in recent living memory. From Microsoft.
