> That's ominously sounding bullshit. You decide what to do with your willpower, and if you don't like the consequences, it's your fault, not some nefarious engineers.

This is simply a fallacy. You can’t decide to switch off selective psychological mechanisms in your brain.

Facebook, Snapchat etc. are weaponizing and exploiting these against us/humanity in ways similar to Vegas casinos.

It is easy to not drive to Vegas, enter a casino and engage in a psychological loop designed to hack my brain.

It is not so easy to escape the all-permeating tentacles of social media and its finely tuned intermittent rewards etc. mechanisms.

Given that willpower is a limited cognitive resource, your proposition is not realistic.
