There are lots of examples of where personalization results in a worse experience for users but better metrics for the tech company.

Somehow the Instagram ads algorithm has figured out exactly what I’m self conscious about with my own body; all I see are ads for invisible braces, skin cleansers, and hair treatments.

I don’t actually want to buy any of these things, and they make me feel bad to look at. A de-personalized Instagram experience would be far superior to me.
