The book was not written as a critique. It was written as a how-to guide. That is precisely why it matters: it named and systematized the design patterns that DarkBadge measures, from an insider's perspective, before most users were aware these patterns existed.
Eyal has since written Indistractable (2019), arguing that individuals have more control than the Hooked framework implies. The debate about how much is design versus individual agency continues — DarkBadge takes the position that the design matters, that the patterns are measurable, and that consumers deserve to see the score.
