Meta and YouTube Found Liable for Social Media Addiction in Landmark California Verdict

Reuters reports that a Los Angeles jury ordered Meta to pay $6 million to Kaley, finding Meta 70% responsible and YouTube 30%. The seven-week trial argued that design features such as infinite scroll, autoplay, algorithmic notifications, and beauty filters fostered addiction and worsened Kaley's depression and anxiety. TikTok and Snap were named but settled before trial; both Meta and YouTube said they would appeal. The verdict is the first of three bellwether California state trials and could influence broader debates over platform liability. The same day, a New Mexico jury ordered Meta to pay $375 million for failing to protect children on Instagram and Facebook. Source: Reuters

Overview

A landmark California verdict found Meta and YouTube negligent in the design and operation of their platforms, with Kaley (KGM) awarded $6 million in damages—$3 million compensatory and $3 million punitive. The jury assigned 70% of responsibility to Meta and 30% to YouTube, setting the stage for potential appeals by both companies.

Evidence and Internal Documents

The trial exposed internal Meta documents suggesting a strategic push to engage younger users, including a memo that stated, "If we wanna win big with teens, we must bring them in as tweens" and data showing that 11-year-olds were four times more likely to return to Instagram than competing apps, despite a 13-year minimum age requirement. These materials were used to argue that platform design, not user posts, caused harm.

Kaley's Background and the Lawsuit

Kaley filed her lawsuit in 2023 at age 17, alleging that features such as infinite scroll, autoplay, notifications timed by algorithms, and beauty filters contributed to addiction and worsened her mental-health conditions, including depression and body dysmorphia.

Verdict, Reactions and Implications

The verdict marks a sharp shift in the legal landscape around social-media liability. Meta will pay $4.2 million and Google/YouTube $1.8 million, with both companies signaling appeals. The ruling follows another legal development the previous day in New Mexico, where Meta was ordered to pay $375 million for failing to protect children on Instagram and Facebook. The California case is the first bellwether in a larger pool of more than 1,600 plaintiffs and will influence how juries respond to core arguments about platform design and responsibility.

Broader Context and Next Steps

Experts say the verdict could have broad consequences beyond Kaley’s case, potentially shaping future litigation strategies and policy discussions around Section 230 of the Communications Decency Act and the debate over whether platforms should be treated as products or publishers. Meta and YouTube have indicated they plan to appeal, underscoring the ongoing tension between tech platforms, the courts, and policymakers regarding the responsibility for design choices that drive engagement.
