Meta Platforms (META) CEO Mark Zuckerberg testified before a Los Angeles court on Wednesday in a civil lawsuit claiming the tech giant’s social media platforms — such as Instagram and Facebook — harm younger users and get them addicted to the apps.

Penn State Dickinson Law associate dean Daryl Lim comes on Market Domination Overtime to explain the points of the case, the criteria jurors will be deciding, and what the case’s ruling will ultimately mean for both Big Tech and social media companies.

Meta’s chief executive Mark Zuckerberg is currently testifying in court in Los Angeles. This is part of a landmark civil lawsuit that accuses Meta’s platforms of getting younger users addicted to them and in turn, damaging their mental health. It is a case that could have huge impacts for the future of social media companies. So let’s unpack the social and legal issues of the trial. Join me now, we’ve got Daryl Lim. He is an associate Dean at Penn State Dickinson Law. Daryl, it is great to see you. So, you know, one way this case is kind of being talked about, Daryl and discussed is folks saying this is really kind of like social media’s big tobacco moment, Daryl. You know, that’s how it’s being framed. I’m just curious when you hear that, do you think, you know, that’s fair, that’s accurate or or no, that sounds exaggerated. I mean, do you do you do you hear similarities, Daryl?

01:12 Daryl Lim

Well, Josh, first of all, it’s great to be with you. Uh I think there’s something certainly to be said about the major shift in how courts are looking at social media companies. Traditionally, these lawsuits against social media companies have focused on content that’s posted by users. This case is different because the plaintiffs are arguing that the platform design itself, features that we are familiar with like infinite scroll, like the recommendations that they put out, the notifications, these were intentionally engineered to maximize engagement by users in ways that could have contributed to compulsive use, especially among minors. And legally speaking, that distinction is critical because the claim is no longer just about speech, it’s about whether the product itself was designed in a way that created foreseeable harm. So, at its core, the case that you just described really talks about whether social media platforms are more like passive communication tools or are they engineered products that are designed to shape behavior. And if juries conclude that and engagement driven design choices create foreseeable harm, that could fundamentally change the legal responsibilities of tech companies.

02:27 Josh

So is the heart of the legal matter, Daryl, um in simple layman’s terms, correct me if I’m mischaracterizing, is it okay, jurors have to decide if there was harm and then if there was harm, was that caused by Big Tech’s product design or was it caused by third-party content? Because if it’s the latter, Daryl, then they have immunity under Section 230. Am I am I framing that correctly?

03:00 Daryl Lim

Right. So, you have pointed exactly the nub of the issue. What makes this case different is that it targets platform architecture and not user content. The earlier lawsuits they often fail because of section 230, which protects platforms from liability for third party speech. But Section 230 does not shield companies necessarily from liability for their own product design. and that’s exactly what the plaintiffs are arguing that these creatures that I mentioned are design choices that the company itself has made and that shifts the legal question from content moderation to product safety. And that’s a fundamentally different legal framework.

03:54 Josh

Is there a clear medical definition, Daryl of social media addiction that is accepted by lawyers and physicians?

04:08 Daryl Lim

Well, I think this is a quickly moving, evolving landscape. I think what the uh court will decide in this case will help shape that definition. I don’t think there’s anything that’s settled that’s bulletproof, that’s beyond dispute right now.

04:29 Josh

Mark Zuckerberg testifying, Daryl, I’m curious when you have such a high profile CEO take the stand like that. Um what kind of impact, what kind of influence can that have on a case like this on a jury?

04:47 Daryl Lim

Uh huge. I think his testimony is critical because these cases will turn on intent and design. And as you mentioned, Mark Zuckerberg has now testified and he’s testified that increasing engagement was not it matters goal. That was a key legal defense because intent matters. And if engagement is simply a secondary operational metric, it’s there. Uh the defense can argue that the platform was designed for legitimate purposes like communication and connection. In fact, Mark Zuckerberg says the reason why users are as engaged as they are is because they see value in the design of the system. It’s not that it’s engineered to promote addiction. And that is a uh a dueling narrative that the plaintiffs will have to respond to.

05:43 Josh

Let’s say Daryl, the jury does ultimately side with the plaintiff. What could that mean for these big tech companies? I mean, what what are we talking about here? Is it big financial liabilities, Daryl, is it uh changing the algorithm? What what are some possible consequences?

06:05 Daryl Lim

Well, you know, this trial is widely viewed as a bellwether for hundreds of similar lawsuits and that verdict could influence how courts across the country look at platform design and liability. And of course, as you rightly alluded to, this could mean uh huge damages potentially, but I think more importantly for the companies as a business proposition, these design choices could carry legal liability risks. They could be walking into an unknown minefield. It could encourage companies to redesign engagement features, it could encourage them to implement stronger safeguards. all that sounds good, but it it means that we are starting a domino effect of which we don’t know what’s going to happen eventually. But importantly, this could also accelerate what’s already brewing in the regulatory space of lawmakers, uh thinking of introducing clearer standards for transparency and youth protection. So there’s going to be, I think uh the beginnings of a structural shift on how digital platforms are designed and governed not just in this country, but often because what happens in this country ripples out to the rest of the world, it’s going to have global impact as well.

07:22 Josh

Yeah, that I guess my last question, Daryl, kind of leading me where I was going because I, I was going to ask, okay, well on the other hand, let’s say the company wins, Zuckerberg comes out on top. I guess would that really be a win, Daryl or are you saying, listen, you’re, you’re inevitably you’re going to see more lawsuits, tougher regulatory oversight is on the way.

07:49 Daryl Lim

I think you put it well, uh what first of all, a win at the court is still a win at the court, whether it’s going to signal is that courts will remain cautious about expanding liability for emerging technology. And then I think you have seen as a consistent uh trend in how it has approached other issues. But even in that scenario, that trend towards platform accountability will continue whether from regulators, whether from public pressure, whether from Congress and this is really the first of a long battle that we will see between tech companies and users and all the other stakeholders involved in this enterprise.

08:52 Josh

Big, important, complicated story. Daryl, thanks for helping us think through it. Appreciate it.

09:02 Daryl Lim

My pleasure.
