En Californie, un procès civil très suivi met Meta et Google sous pression : Instagram et YouTube accusés de créer une dépendance chez les jeunes, avec des conséquences possibles sur la santé mentale et sur l’avenir du design des plateformes. Voici les mécanismes visés, les enjeux juridiques et les impacts concrets à surveiller.
The controversy surrounding digital addiction is no longer confined to public debate; it is now playing out in a Los Angeles courtroom, in a case that could set a precedent. The case is distinguished by one key point: it does not target published content, but rather the design platforms.
Between recommendation algorithms, automatic reading and notifications, the arguments put forward point to a central question: have the major platforms optimized the attention of minors to the point of making it a predictable and avoidable risk?
Los Angeles trial: Why Instagram and YouTube, accused of creating addiction among young people, are a game changer
The civil trial opened in Los Angeles places Meta (Instagram) and Google (YouTube) in front of a fundamental accusation: Instagram and YouTube accused of creating addiction among young people This would not be a simple side effect, but a design choice. The plaintiff, a young Californian now 20 years old, describes an early and continuous history of use: YouTube from childhood, Instagram at the start of adolescence, then the accumulation of other social applications over the years.
The core of the case rests on a cause-and-effect chain: prolonged exposure, reinforcement of routines, then the onset of reported symptoms such as depression, l'anxiety and body image problemsIn this context, the legal strategy aims to show that addiction is not just an individual weakness, but a statistically expected outcome when the interface constantly pushes one to “stay a little longer”.
A crucial element concerns the US legal border: Section 230 of the Communications Decency Act largely protects platforms from content posted by third parties. Here, the attack circumvents this shield by targeting the “product” itself, that is, the features and the commitment logicThe question posed to the jurors then becomes more industrial than moral: can a design oriented towards the past be considered a wrongful choice when it affects minors?
The trial is also being viewed as a test procedureIn California, numerous similar lawsuits are reportedly pending, with a potential domino effect if design responsibility is established. TikTok and Snapchat, initially cited, are said to have opted for a confidential settlement, which reinforces the focus on Meta and Google and amplifies the symbolic reach of the audience.
To understand the background context, it is helpful to link this case to the signals already documented on the behavioral addictions related to platforms, particularly when a product optimizes attention as an economic resource. Further insights can be found in this analysis on social media addictionwhich helps to situate the debate between psychology, design and business incentives.
What is happening now naturally foreshadows what follows: if the law is concerned with the product, then it is necessary to precisely dissect the concrete mechanisms involved.
Algorithms, notifications, autoplay: the mechanisms targeted when Instagram and YouTube are accused of creating addiction among young people
In this case, the debate shifts to a highly technical area: how can individual, "neutral" product components form an attention-capturing system? When we talk aboutInstagram and YouTube accused of creating addiction among young peopleThe accusations mention known growth levers: the algorithmic recommendationthe notificationsthe personalization flows and the automatic reading.
The recommendation system acts like a funnel. A minor starts with commonplace content (music, humor, tutorials), then the algorithm refines, speeds up, and specializes. The user doesn't feel like they're choosing a direction; rather, the feed "finds" what's relevant. In a typical scenario observed by parents, a middle school student opens YouTube for a review video and finds themselves 40 minutes later watching unrelated content because the sequence has been optimized to minimize friction.
Notifications, on the other hand, act as external reminders: they interrupt off-screen activity and reintroduce a social stimulus (message, like, comment, new video). Design becomes persuasive when the notification no longer simply informs, but prompts a quick reaction. It is precisely this "reflexive" dimension that is highlighted: the gesture of unlocking the phone sometimes precedes a conscious decision.
Autoplay amplifies this phenomenon further by eliminating any moment when one could stop. On YouTube, moving from one video to the next becomes “natural,” even though it's a conscious product selection. On Instagram, infinite scrolling offers a similar mechanism: as long as the thumb is moving, stopping is never forced. In an adolescent context, where self-regulation is still developing, the removal of exit points changes everything.
To make these concepts easier to understand, a table helps to distinguish functionality, business objective and specific risk when minors are exposed.
| Platform mechanism | Desired effect (engagement) | Associated risk in minors | Concrete example of use |
|---|---|---|---|
| Recommendation algorithm | Increase session time | Trapped in a loop of content, perceived loss of control | Video “next suggestion” aligned with micro-preferences |
| Push notifications | Restart daily returns | Interruptions, impulsiveness, difficulty hanging up | “New comment” received during homework |
| Automatic reading | Reduce breaks | Involuntary lengthening of past time | A series of videos without user interaction |
| Customizing the feed | Maximize relevance | Overexposure to aesthetic standards, social comparison | Instagram feed focused on body, fashion, “before/after” |
In the documents cited at trial, the prosecution also reportedly relied on internal documents referring to...addiction as an objective or indicator to be monitored, as well as on exchanges where the engagement of younger people would be explicitly sought. This type of element, when credible, changes the interpretation: it is no longer a “deviation”, but a product intention.
To delve deeper into algorithmic logic, which is useful both for understanding the process and for interpreting the choices made by the platforms, this article on the power of algorithms and communities sheds light on how recommendation systems transform simple content into a usage trajectory.
La suite logique consiste à examiner ce que cette judiciarisation implique pour les marques, les créateurs et la sécurité des adolescents, car la responsabilité du design influence aussi les pratiques de marketing d’influence.
Possible consequences for adolescent safety, influence, and advertising if Instagram and YouTube, accused of creating addiction among young people, win their case
If the court recognizes design-related liability, the effect would not be limited to damages. Such a signal could push platforms to modify design parameters and force ecosystems (advertisers, agencies, creators) to adjust their practices. This is where the expression Instagram and YouTube accused of creating addiction among young people becomes a market issue: attention, targeting, compliance and reputation are all linked.
From the platforms' perspective, a plausible solution would involve stricter settings for teen accounts: reducing certain notifications, forcing pauses, setting session limits, or offering less aggressive recommendations on sensitive topics. For a brand, this means potentially less "easy" reach to achieve, but higher-quality exposure if the environment is perceived as healthier. A concrete example: a sports brand targeting high school students could see a decrease in "impulse" impressions while gaining parental trust, which improves the conversion rate in the long run.
From the creators' perspective, the impact is evident in how they construct their formats. Highly aggressive, "hook-and-click" content, designed to prevent viewers from stopping, could be subject to greater scrutiny. Conversely, content with clear value (tutorials, advice, skillful storytelling) fares better because it doesn't rely solely on clickbait tactics. In practice, an educational creator can secure their growth by structuring their videos with explicit objectives, time markers, and a less shock-driven pace.
This transformation also affects monetization. The advertising model relies on attention, so any time limit changes the game. Advertisers will demand greater transparency: which placements are shown to minors, in what contexts, and with what guarantees?

In the area of adolescent protection, the California case reinforces a trend: safety is becoming a central argument, not just a constraint. Parents and schools expect evidence of efforts. For brands, the reputational risk is simple: appearing alongside a mechanism perceived as addictive can be enough to trigger negative publicity.

A common thread allows us to visualize the trade-offs. Let's take the fictional case of a Californian "clean" cosmetics startup that wants to attract a 14-18 year old audience. By 2026, its most robust strategy consists of requiring content creators to include messages about moderation (screen time, self-esteem), prioritizing placements in valuable content (skincare routines, ingredient science), and accepting less explosive but more sustainable growth. The trial then acts as a reminder: simply optimizing attention can no longer be the only credible KPI.
