Episode: Big Tech on Trial: A Mother Speaks // Julianna Arnold
Date: March 18, 2026
Host: Hillary Wilkinson
Guest: Julianna Arnold

Overview

This episode departs from the Healthy Screen Habits’ usual avoidance of headline news to focus on a pressing and deeply personal topic: a landmark court case in Los Angeles challenging whether major tech and social media companies like Instagram and YouTube can be held liable for addictive and harmful platform designs. Host Hillary Wilkinson interviews Juliana Arnold—a mother who lost her daughter, Coco, to fentanyl poisoning following exploitation and addiction fueled by social media design—to gain an inside perspective on the realities faced by families affected by online harms and the fight for accountability.

Key Discussion Points & Insights

Juliana Arnold’s Story and Motivation

• Personal Tragedy as a Catalyst

  • Juliana recounts losing her 17-year-old daughter, Coco, in 2022 after Coco was approached and groomed online by a man on Instagram. The man lured her out under false pretenses, ultimately providing her with fentanyl disguised as Percocet, resulting in Coco’s death.
  • Quote [03:15, Juliana Arnold]:

    "She left the house that morning at, like, 11 o'clock, saying she was going thrifting with her friend, and she never came home. Whatever she was given, the pill was not Percocet. It was Fentanyl. And she died from fentanyl poisoning."

• Struggles with Platform Addiction and Parental Controls

  • Juliana describes feeling helpless as her daughter became deeply engaged and, at times, addicted to various platforms, noting particular vulnerabilities among kids with learning differences.
  • Describes the futility of trying to monitor or police her child’s online activity, likening it to "whack-a-mole".
  • Quote [05:25, Juliana Arnold]:

    "Maybe they have more than one account. You know, they're better at this than we are...I did the best I could, but it was so frustrating."

• Turning to Advocacy

  • After meeting other survivor parents, including Deb Schmil, Juliana became involved with the Online Harms Prevention Group at Fairplay and advocacy for legislative change.
  • Quote [06:22, Juliana Arnold]:

    "I knew that if I was going to advocate and wanted to do something meaningful, this is what it was going to be."

The Legal Landscape: Understanding the Case

• Why Los Angeles?

  • The landmark case is being heard in LA's Superior Court due to California’s reputation for being receptive to these complex issues and the state’s judicial council coordinated proceeding (JCCP) framework.
  • JCCP consolidates related cases, with one selected as a “bellwether” to establish precedent for others.

• Bellwether Case Structure

  • Juliana explains the difference between JCCP (state-based, not class action) and MDL (national, multi-district litigation).

• Product Liability vs. Section 230

  • The heart of the case: Plaintiffs argue not about user content, but about intentional, harmful design features of social media platforms.
  • Section 230 of the Communications Decency Act has historically shielded tech companies from liability for user content—likened to a "blackboard" or public bulletin board.
  • The current case avoids this shield by focusing instead on product design and safety, not user content.
  • Quote [09:25, Juliana Arnold]:

    "It's solely about the design of the platforms and that these companies knew the harm that their platforms are causing, but intentionally designed them to be addictive so they could increase their viewership among young users and then increase their profitability..."

• Impact of Discovery Process

  • For the first time, internal documents are being released showing intentional addictive design choices, validating anecdotal accounts by families.
  • Quote [12:12, Juliana Arnold]:

    "It’s really providing the internal documentation that is starting to show that this, in fact, was an intentional design feature... and there’s never been anything to stop them because they have full immunity behind 230."

In the Courtroom: Personal & Tactical Challenges

• Parental Presence and Advocacy in Court

  • Survivor parents prioritize being present in court to ensure tech executives see the faces behind the tragedies, despite limited seating and attempts (rumored) by tech companies to block their court access.
  • Quote [16:13, Juliana Arnold]:

    "We really, really, really felt strongly that the first thing he saw was a whole row of survivor parents just present... That next morning when Adam Mosseri testified, we were the front row. And he was looking at 12 survivor parents. And I think he knew exactly who he was looking at."

• Executives’ Testimony and Tactics

  • While executives like Adam Mosseri and Mark Zuckerberg have been compelled to testify, Juliana describes their responses as highly coached and evasive, rarely providing substantive answers.
  • Reference to Congressional hearings, including Zuckerberg’s forced apology to parents.

• Revelations and the Importance of Ongoing Litigation

  • Additional internal documents continue to be unveiled, contributing to a growing case for reform and real accountability.
  • Growing hope that sustained exposure will push lawmakers to establish "guardrails" and force companies to design safer products.
  • Quote [19:34, Juliana Arnold]:

    "Our hope is that as parents and legislators start to see...the inner workings...they're just going to have to put their foot down and do their jobs, which is, you know, put guardrails on these companies so we can keep our kids safe and force them to design products that are not deadly or harmful..."

Memorable Moments & Quotes

• On the Plaintiffs’ Legal Team
  • Juliana is impressed by the plaintiff’s attorney, trained as a pastor, who skillfully translates complex legal and technical details into compelling, understandable stories for the jury.
  • Quote [20:46, Juliana Arnold]:

    "Talk about addicting. I was, like, totally hooked...because also, the litigator for the plaintiff...just presents everything in a way. He's telling a story...really has an amazing way to make something that's probably pretty complicated, pretty simple."
