The original implementation of iCloud included Apple's ability to recover the data. You can view this as a backdoor, and that might be fair, but the reality is that it's also a feature in the eyes of many customers - because people will lose devices and passwords, and when Apple doesn't have the keys that means they also lose data. Many customers would rather be able to get their data back.

Apple has moved more things into the bucket of "we do not have the keys for this" over time, but pretending that this isn't a tradeoff for the common customer is disingenuous. That's why ADP exists, so that those who want to make a different tradeoff can do so.

Commenters on HN tend to be technically savvy and tend to want the defaults to be tailored to a technically savvy customer base. That's fine, but that's not a real representation of all of the smartphone users out there, and in this case Apple is directly offering the choice that they usually get knocked for taking away.
