Is social media addictive? And are social media companies liable?

Summary

This Marketplace Tech episode has Eric Goldman explain a Los Angeles lawsuit alleging that social media companies intentionally designed addictive products that harmed children and teenagers. Meta and YouTube deny the allegations, while [[Snapchat|Snap]] and TikTok reportedly settled. The episode extends Social Media Product Liability by focusing on Platform Legal Causation, the appeal-stage role of Section 230, and the risk that social-media addiction theories become Internet Liability Spillover for other interactive products.

Key Claims

• The lawsuit alleges that social media companies intentionally designed addictive platforms that harmed children and teenagers’ mental health.
• Meta and YouTube are defendants in the case and deny the allegations; [[Snapchat|Snap]] and TikTok reportedly settled.
• Goldman says the case is part of a wider wave, including a federal California matter with thousands of plaintiffs, school districts, state attorneys general, Native American tribes, and a related New Mexico attorney general case.
• The plaintiffs’ hardest task is not only showing that young people were harmed or that companies knew of risk; they must show that defendants legally caused the harm.
• The trial tests whether jurors accept “social media addiction” as a real injury category and whether platform services can be held legally responsible for resulting harms.
• Goldman argues that legal pressure could change internet product design, including tools that shape how users find, consume, and communicate around content.
• The legal theories are aimed at social media first but may be deployed against video game makers, generative AI model makers, and other interactive internet services.
• Section 230 is not part of the immediate jury trial because the judge already accepted some defense arguments and rejected others, but Goldman expects the issue to return on appeal.
• Goldman frames the stakes for users as well as companies: people may face paid services, fewer legally resilient platforms, or reduced functionality if liability exposure changes the economics of user communication.

• Section 230 - platform-immunity doctrine excluded from the jury phase but expected on appeal.

Contradictions

• No direct contradiction found with existing wiki content.
• Timeline note: this February 5, 2026 source discusses the Los Angeles litigation before the March 27, 2026 Marketplace Tech Bytes episode reports a negligence verdict against Meta and YouTube. Treat the February source as the pre-verdict framing of the same broader litigation branch.
• The source qualifies later social-media liability pages by emphasizing uncertainty at trial: the jury still had to assess addiction, causation, and responsibility, while Section 230 was deferred rather than resolved.
