> and then they engage with the app less or even churn

I wasn't aware engagement maximisation is the reason we don't get customization options anymore, but it makes perfect sense.

No one used to care about this because it was at the discretion of the user whether they want to keep using the app or not. Whereas today, it's the company objective to keep the user in the app as much as possible.

I remember the miniform of media players. Because while you need the full interface while managing playlists, you only need a few button and some status when you’re playing music. I don’t think Spotify will ever implement that feature.
