I do not think there is a right answer in that a feed can be designed with many sorts of characteristics and still be seen as an attractive feed to the user. For instance a feed could show you fashionable upcycling, reuse, repair, thrifting, etc. or it could show you stuff you could buy new at Rodeo Drive , Wal-Mart, Temu, etc. If the feed creator cared they could collect train/test data and make a model that predicts that variable and be able to quantify it as a property of the feed that can be optimized for.

Interaction with the feed also creates a record (more so if the user writes something) of the subject’s mental state including both chronic and acute disorders, stress, anxiety, depression as well as psychosis symptoms.

That responsibility is awesome, it is hard to defend “doing nothing” with this information as an ethical policy but any intervention is likely to be ill-targeted, ineffective and ethically questionable in its own way.
