Meta has reached a landmark settlement with a bipartisan coalition of 52 state attorneys general, agreeing to pay up to $18 billion over 10 years and implement significant changes to how young users interact with its platforms, Instagram and Facebook. The settlement addresses accusations that Meta designed its products to be addictive for children.

The agreement, announced Wednesday, aims to create a safer online environment for minors by introducing new default settings and features. This resolution comes after a high-profile federal case in Oakland, California, which began last week, accusing Meta of knowingly creating dangerous products for young users and misrepresenting their safety.

Key provisions of the settlement include a default daily time limit of two hours for users under 18, which parents can override. Additionally, Meta will stop displaying the number of likes or reactions for young users and will offer an optional non-personalized feed. This feed will not use algorithms designed to keep users scrolling, a practice central to the lawsuit's claims.

While Meta did not admit wrongdoing as part of the settlement, the company stated it partnered with state attorneys general to establish a new industry standard for user safety. "Ensuring teens have a safe and productive experience on our platforms is an absolute imperative for Meta. We want to get this right for parents and teens," the company said in a statement.

The settlement marks a significant development in the ongoing scrutiny of social media's impact on youth mental health. State attorneys general had argued that Meta understood the addictive nature of its platforms and its potential harm to adolescents, yet continued to promote them. The company had previously denied these claims, asserting that it had implemented protections for younger users.

This agreement follows a separate case in New Mexico, where a judge ruled last month that Meta contributed to a youth mental health crisis and ordered the company to pay $567 million, a decision Meta has stated it intends to appeal. The federal settlement must still receive court approval, and notably excludes New Mexico and Florida.

The settlement was reached just one day after testimony from Adam Mosseri, the head of Instagram, who denied hiding information about the app's safety. The ongoing legal challenges highlight the increasing pressure on tech giants to address the societal impacts of their platforms, particularly concerning their youngest and most vulnerable users.

With the proposed settlement, Meta faces substantial financial obligations and mandated changes to its core products. The long-term implications for user engagement and Meta's business model, especially concerning its youth demographic, remain to be seen as the new policies are implemented and monitored.
