The same thing happens with in-app purchases.

A friend of mine worked at Disney, and it is insane how much data they capture on their players/spenders and how they use it for the sole purpose of triggering a popup at the right time, at the right price, that would maximize spending/gambling on loot boxes.

The first time I heard "whale" mentioned in the video game space was at a GDC panel around a game called Puzzle Pirates, where the dev noted that the bulk of their in-game purchases were made by a small group of "whale" players. In 2003 purchasable skins, pets, hats, etc were pretty new.

Algorithmic optimisation will be the death of us.

Over-dramatic? Maybe, but this thought springs to my mind more and more.
