I'd personally target the "source" of the addictiveness: outlaw behavioral analytics that, on those apps, analyse any detail of your navigation (how fast you scroll, where you stop etc.).<p>A: Many people are not aware that's a thing: "I did not click like on a racist video, but it keeps showing them to me", when in reality, the algorithm detected that you slowed down when shown that type of content so decided to feed more of it to you.<p>B: I targets your worse instinct (oh a half naked girl, maybe she has something interesting to say?), and if you're not aware of point A, it's a loosing battle. If you are aware of point A, it's constantly tiring to have to adjust you speed scroll etc.<p>I would personally make a GDPR type law that would require:
"Any feed of user data must be presented in a non-opaque way, such as chronological, ranked by upvotes etc. Any personalized feed based on expectations of user preference should be entirely transparent, by allowing the user to access, modify their profile, as well as locking them (preventing future behaviour from changing the type of content you see).
