I do not see it this way. I have great parents: smart, non overbearing but always ready to help. But I still listened to the strangers (and friends and family, and probably ignored 80% of all that advice). Some thoughts on why this could make sense:

First, I probably know what a family member would suggest (by being close, observation, partial answers of related questions). That "indirect advice" is already baked in. Second, more data points can helps. Last but not least, with family and friends you lack anonymity and it could be nontrivial to ignore advice of a family member on a serious matter. I do not see any of this as dystopian.

As an anecdote, where I grew up train travel was common, generally safe and tickets cheap (and at 16 you were a full adult and can go alone wherever you want / can afford). On long train rides folks would often discuss things and open up in a way they would not do with a close friend. "Train conversations" was a phrase in common use suggesting it was not rare.
