Everything else outside of reels is the usual social media fake life facade, and everything amplified to the max for engagement to get it pushed to feeds via "the algorithm" (note: Interactions don't need to be positive to promote it to feeds)
Rewind 30 years or so, how long did the typical New York Times subscriber spend with their paper every day?
Was the Times addictive?
And I won’t even get started on network television for half a century.
Lots of people can get drunk once a month and suffer or cause no real harm. Some people get drunk everyday which is slightly more harmful.
There are many physical products that are today designed to minimize harm and misuse after facing liability historically. So I suppose the direct answer to your question would be "yes, absolutely, and there's a figurative mountain of precedent for it".
There’s somebody out there who’s harmfully addicted to just about anything, from ultramarathons to World of Warcraft.
What’s the limiting principle on liability?
The limiting principle on liability is quite complicated. You'd have to go ask a lawyer. At least in the US (and I believe most of the western world) it has to do with manufacturer intent, manufacturer awareness, viable alternatives, and material harm among other things.
Doritos are designed to taste good and encourage you to eat them to your satisfaction.
The latest Mario game is designed to be playable & fun for as long as you have time and energy to play it.
My Instagram feed is designed to engage me with interesting and relevant content for as long as I have time to scroll.
All three can be used in unhealthy ways, and would be less likely to be so used if they were designed less well to their goals.
Which is “designed to be addictive”?
It doesn't matter if the outcome is the same here what matters is the intent behind the design when considered in the context of the intended usecase. That's in addition to lots of other factors (some of which I listed) plus any relevant legislation plus any relevant case law and that will all be examined in great detail by a court. At the end of the day what is legal and what is not is decided by that process. A large part of the point of employing corporate lawyers is to prevent a situation where your past behavior is examined from arising in the first place.
I'd suggest the essay "what color are your bits" if you're genuinely struggling to understand this concept.
I’m asking what that means.
If your answer is, “Only the lawyers can tell us,” then that’s not particularly satisfying if we want to live in a world where how we choose to spend our time is not under the supervision of some elect.
It's hard to explain black holes, especially in a hackernews text box, but that doesn't make them irrelevant.
At the end of the day it doesn't truly matter if there was intent before we regulate it. If I mix random chemicals/foods/etc and end up with an addictive drug like alcohol, we don't need to try to prove it was intentional before we start considering the harm it causes to society.
