You are missing the point and are confusing real-world applications with SEO-optimised websites and e-commerce apps. Besides if anything, dark patterns, tracking etc. are pushed mainly by the product mgmt. sect, a group which I agree has had a lot of toxic impact and is mentality-wise closer to the monkey-banana-hoarders than to their engineering peers.They share the same lack of competence, unfounded arrogance and tunnel vision with the likes of Uncle Warren. It all has nothing to do with the genuine, intrinsic motivation of an engineer.
