There goes that nasty evil capitalism, "It wasn't my lack of will power and cognitive short falls that caused me to buy these things ... it was capitalism's fault. I'm completely innocent and would never make bad decisions of my own accord ..."
That is somewhat unfair. Most of the time, it’s a naive consumer on one side, and an army of UI experts and behavioral scientists on the other. That consumer is hopelessly outmatched, and the company will absolutely find a way to hack his or her psychology.
If this were loot boxes, then maybe we'd be having a different discussion, but unless they're tricking you into something other than what is advertised, then the onus ultimately falls upon you to control your desire to purchase something.
