The primary purpose of making an addictive product is to remove peoples' agency by hijacking known deficiencies in our minds/bodies. It's a form of coercion, because your goal is to prevent people from being able to choose whether they use your product or not.
If they aim to remove agency, it's because you have it in the first place, meaning you can stop it from happening with proper information.
I understand that some people might not understand they are being targeted and should be clearly told what could happen to them. But the majority of people must know FB is addictive.
After that, I can't see how people still getting addicted is the company's fault.
Well, when the product is mis-information that has been carefully tailored, evolved and tested to counteract proper information...
