Why It Matters: This filing sharpens three doctrinal pressure points simultaneously. First, by framing Meta's UX and algorithmic architecture as standalone liability-generating conduct divorced from the third-party content they deliver, the AGs are asking the court to draw — at summary judgment and as a matter of law — the line between immunized content-presentation choices and non-immunized product design that courts have struggled to locate since the *Instagram MDL* proceedings. Second, the COPPA actual-knowledge argument, if credited, would represent one of the first Article III holdings imposing COPPA liability on a major platform through litigation rather than consent decree, generating immediate pressure for circuit-level resolution. Third, the "directed to children" theory applied to a general-audience platform with heavy minor usership pushes the § 312.2 definition well beyond prior FTC enforcement targets, and if adopted, would effectively require any platform with substantial underage engagement to comply with COPPA's full consent regime regardless of marketing intent — a structural shift with industry-wide consequences.

Why It Matters: Meta's central defense at summary judgment is that Section 230 extinguishes the states' consumer protection claims before they can reach a jury, on the theory that those claims would effectively hold Meta liable as a publisher of harmful user-generated content. The Massachusetts Supreme Court — one of the most respected state courts of last resort in the country — just rejected that argument in a case involving the same defendant and a structurally similar legal theory, and Plaintiffs are placing that ruling before the MDL judge at the earliest opportunity. Whether it moves the needle depends on how closely the Massachusetts claims and pleadings track those at issue in the MDL, a question the filing conspicuously leaves unaddressed and that Meta will almost certainly contest. The filing also signals a deliberate multi-forum strategy by the state AGs: collecting appellate-level authority across jurisdictions to build persuasive momentum against Section 230 preemption — a campaign worth watching as similar litigation proceeds in other states.

Why It Matters: The opinion is the most prominent state appellate-court decision to date to categorically hold that Section 230 does not immunize platform design-defect or product-deception claims, and it does so through a textually grounded, common-law publisher framework that is methodologically distinct from — and directly contests — the reasoning this MDL court has previously applied. By naming and rejecting the MDL court's prior rulings, the SJC supplies a reasoned, appellate-level counter-analysis that, while not binding in federal court, materially reduces those rulings' persuasive authority and gives this Court a fully developed alternative framework to consider when resolving the pending motion. The procedural holding — that Section 230 immunity supports interlocutory appeal under the present-execution doctrine — also signals that state courts of last resort are prepared to treat Section 230 as a true immunity from suit, consistent with federal consensus but now carrying explicit state appellate endorsement. What remains open is whether this Court will credit the SJC's common-law publisher test over its own prior analysis, a question that will be resolved when it rules on Related Doc. 266.

Why It Matters: This filing maps the most actively contested doctrinal fault line in the social-media MDL: whether Section 230 immunity can reach a platform's own affirmative misrepresentations when those statements concern how the platform manages third-party content, and whether that immunity argument can be revived at the in limine stage after lying dormant through dismissal and summary judgment. The AGs' reading of *Bride* and *Grindr* — confining those decisions to publisher-role claims — is doctrinally significant but contested; if Meta persuades the court that misrepresentations about content moderation are inherently representations about third-party content handling, a substantial category of deception-based claims could be imperiled. The procedural forfeiture theory, if credited, would be a notable development in MDL practice, signaling that Section 230 must be raised and preserved at the dispositive-motion stage or risk being treated as waived. A ruling on this motion — in either direction — is likely to produce Ninth Circuit guidance that will either solidify the misrepresentation carve-out as a clean doctrinal category or begin to erode it where editorial and deceptive conduct are intertwined.

Why It Matters: This brief is a significant pre-trial marker in one of the highest-stakes social media liability cases currently in active litigation, because it attempts to establish at the evidentiary level — not merely the pleading level — that internal corporate documents about design alternatives are fully accessible to plaintiffs at trial regardless of any residual Section 230 argument. If the court denies Meta's motion and admits this evidence, it will confirm that state AG consumer protection claims can reach deep into a platform's internal deliberations, and it will consolidate a procedural norm — that a pleading-stage Section 230 ruling forecloses iterative revival of the defense at later stages — with potentially broad consequences across the MDL and for other platform defendants. The "soft-matching" willful-blindness theory is separately worth watching: by framing the harm as deliberate technological underperformance in age verification rather than exposure to any particular content, Plaintiffs present a theory of COPPA-adjacent liability that does not implicate Section 230 at all, and its acceptance or rejection could shape how state unfairness claims are litigated against platforms going forward.

Why It Matters: State attorneys general are suing Meta for allegedly deceiving the public about social media's harms to teenagers, and Meta is attempting to block former employee testimony — including apparent whistleblower accounts — by invoking Section 230, a federal statute designed to shield platforms from liability for content posted by their users. The AGs are pressing a meaningful procedural extension of existing doctrine: if Section 230 does not bar the underlying deception claims at the pleadings or summary judgment stage, they argue, it cannot bar the evidence that proves those claims at trial — translating the "platform's own conduct" carve-out from claim viability into the admissibility context, a step courts have rarely been asked to take explicitly. Whether the court accepts that argument or not, the ruling on this motion will signal how broadly Section 230 can be wielded as an evidentiary tool in MDL proceedings with mixed claim portfolios, where some claims survive the immunity and others do not. A second question worth watching is where the line falls under FRE 701 between a former employee's direct observations about institutional culture and inadmissible opinion testimony about organizational intent — an area where circuit-level authority remains thin.

Why It Matters: Meta's decision to introduce this transcript as its own exhibit while seeking to seal it is the central strategic puzzle: the company appears to be attempting to manage how damaging insider testimony enters the federal record rather than allowing plaintiffs to introduce it on their own terms and framing. The sealing request is legally vulnerable under *Kamakana v. City & County of Honolulu* because the testimony comes from an open state-court trial and carries a strong presumption of public access, particularly where the underlying MIL bears meaningfully on the scope of trial. If the court denies sealing and resolves the MIL against Meta, Boland's acknowledged combination of documented internal knowledge of predictable harm pathways, the suppression of that knowledge, and the direct revenue linkage to the contested algorithmic design could substantially strengthen plaintiffs' corporate-knowledge, concealment, and punitive damages theories across the MDL.

Why It Matters: Meta is attempting something more aggressive than a typical motion in limine: it wants a prior legal ruling that it cannot be held liable for certain features to also mean that witnesses cannot testify about those features at trial — the difference between a court saying "you cannot win on that theory" and saying "the jury cannot hear about it at all." If the court accepts this theory, it could substantially narrow the plaintiffs' trial presentation on core design-defect claims that survived the motion-to-dismiss stage, because the platform features at issue are the same ones underlying the surviving theories. No circuit court appears to have squarely endorsed using a Section 230 immunity ruling as a prospective evidentiary exclusion, making Judge Gonzalez Rogers's ruling on this question potentially the first of its kind in a major platform-liability MDL — and a significant marker for how Section 230 doctrine functions once a case reaches trial.

Why It Matters: Meta is asking the court to block, before trial begins, the evidentiary foundation the California AG would use to show that Meta's conduct was unreasonable — the equivalent of barring a products-liability plaintiff from presenting evidence that a safer design existed. If granted, even partially, this ruling would signal that Section 230 and the First Amendment can together preempt the expert toolkit in state government enforcement actions, with immediate consequences for every AG suit currently pending against social media platforms. The motion also advances a largely untested procedural theory: that Section 230 can function as an *in limine* evidentiary bar, not merely a pleading-stage immunity — a doctrinal expansion that no circuit has squarely endorsed. Judge Gonzalez Rogers's ruling will be closely watched as a potential bellwether on whether platforms can use constitutional and statutory shields to hollow out liability cases without ever reaching a merits trial.

Why It Matters: This filing is worth watching because it maps the outer boundaries of how Meta intends to deploy Section 230, the First Amendment, and evidentiary forfeiture arguments simultaneously to foreclose the State AGs' trial presentation before it begins. The most consequential and legally unsettled move is Meta's effort to extend Section 230 immunity to age-verification mechanisms by characterizing them as publishing decisions — a position that directly conflicts with COPPA's knowledge-based framework and that no circuit court has endorsed. If a trial court adopted that framing, it would generate a significant appellate question about whether Section 230 can insulate platforms from evidentiary scrutiny of their age-detection capabilities in the face of a federal statutory scheme that specifically contemplates that inquiry. The proposed blanket waiver of omission evidence and the categorical exclusion of former employee percipient testimony present additional doctrinal pressure points, since both arguments run against well-established principles that such evidence routinely remains admissible to contextualize affirmative claims and satisfy the personal-knowledge requirements of FRE 701.
