Context
What exactly are the states accusing Meta of?
Four states — California, Colorado, Kentucky and New Jersey — allege Meta knowingly designed features that hook young users, fueling anxiety, depression and suicide, while misleading consumers about safety Reuters,Yahoo! Finance,mint. All 29 plaintiff states also allege Meta improperly collected and used the personal data of children under 13, in violation of federal privacy law Reuters,mint.
How low was the uptake of the safety features?
Internal documents shown to jurors indicated "Take a Break" was used by 1.8 percent of users before it was defaulted on, and "Quiet Mode" also drew limited participation MoneyControl,Yahoo!

A former Meta data scientist, George Volichenko, testified that fewer than 1 percent of teenagers were early adopters and called the tool's initial impact "disappointing" news.bloomberglaw.c…,Bloomberg Business.
Why is this testimony considered significant?
Mosseri is the first top Meta executive to take the stand in what experts describe as the biggest legal test yet of social media's effects on young users Guardian,Reuters,Japan Times. Beyond financial penalties, the state attorneys general are seeking changes to how the platforms operate mint.
Where Left and Right agree, and where they split
- Where Left and Right agree
- Neither framing disputes that "Take a Break" saw low-single-digit teen use before becoming a default in September 2024, and that Meta promoted it without disclosing that.
- Where Left and Right split
- Whether the story is about a company marketing a safety tool it knew teens barely used, or about courts setting product design through $200 billion penalties legislatures never authorized.
- Why they won’t converge
- The divide is evidentiary rather than moral: both sides accept the low-single-digit uptake, but split on whether a tool teens ignored proves deceptive design or merely proves teens' own preferences, a causation question no disclosed number settles.
How left and right read it
A safety feature almost no teen used is not child protection; it is public relations, and that gap is exactly what twenty-nine states are asking a court in Oakland to price. Mosseri conceded usage of "Take a Break" sat in the low single digits before it was finally switched on by default in September 2024, yet that number went undisclosed while the tool was promoted. So make the remedy enforceable: protections on by default, and penalties heavy enough that opt-in gestures stop counting as compliance.
“Slothouber pointed out that just 1.8% of teens signed up for the feature, and that while Mosseri had touted the tool, he never publicly disclosed that number.” — The Guardian
A $200 billion demand is not a safety measure; it is a bet that courtrooms should design products that legislatures have not chosen to regulate. Twenty-nine states allege addictive design, but the evidence pulled forward so far is that a scroll-break prompt saw low-single-digit teen use before becoming a default — thin proof of causation for penalties of that magnitude. Burden of proof still belongs to the accuser.
