Honestly, part of me wants to agree with you whole heartedly but I don't think I can. I started off saying that things like Crack, Nicotine, Alcohol... consumables are addictions. Then what about gambling though... it's not really a physical consumable. Also I have been short-term-addicted to some games, or wanted to binge watch a series, or finish a book despite knowing I have work tomorrow.

As someone who used to smoke, I can't believe that anything is as difficult as stopping smoking, but then Heroin Addicts enter the chat. So whereas to me, it seems incredible that people are addicted to content, it doesn't mean that how they feel about said content doesn't constitute a problem and where that lies on the scale for an individual is impossible to quantify from my narrow viewpoint and experience.

Partial responsibility is a hard thing, it's way easier to blame just one of the parties, but the fact is that both give, and take, and are in a not 100% healthy relationship. The algorithms optimize soullessly for engagement, because what else should they do, hurt the business? Meanwhile, people struggle with willpower, but they themselves are the only ones who can actually do anything about it. Preying on weaknesses is morally reprehensible though, well, maybe not according to machiavellianist people, but still. We regulate subjects of addictive behavior all around the world, realizing that population-wise, it's not the most sustainable ideas.
