Holding Social Media Liable for Terrorism: An Obvious Solution or a Poisoned Chalice?

*Meriam Mossad

I. Introduction

The United States Supreme Court heard oral arguments in Twitter, Inc. v. Taamneh on February 22, 2023.[1] The Court’s ruling could result in liability for internet platforms aiding and abetting terrorism.[2] While civil liability seems sensible to encourage aggressive actions to prevent the use of internet platforms promoting terrorism, this solution would stifle constitutional speech, as platforms would have incentive to remove speech advocating for rights we do not currently have.[3] A ruling in favor of the plaintiff would institute a heckler’s veto and allow the government to censor the internet indirectly.[4]

Nohemi Gonzalez (Gonzalez), a U.S. citizen, was killed in a terrorist attack in Paris, France, in 2015.[5] Gonzalez’s father filed an action against Google, Twitter, and Facebook. The plaintiff claims that all three platforms were liable for aiding and abetting international terrorism by failing to take meaningful action to remove the terrorists’ content. The plaintiff avers that the platforms thus hosted the terrorists’ content, even though they did not play an active role in the performance of international terrorism that actually injured Gonzalez.[6]

II. Collateral Censorship and Heckler’s Veto

First Amendment scholar, Professor Michael Meyerson, has underscored that companies who censor the speech of their customers are not engaging in self-censorship because the companies are not censoring their own speech.[7] Rather, Professor Myerson coined this phenomenon as “collateral censorship.”[8] Collateral censorship occurs when party A controls the speech of party B, and the government holds party A liable for party B’s speech, and in response, party A censors party B’s speech.[9] The risk of collateral censorship from the heckler’s veto is dangerous because intermediaries must often respond to complaints by deleting speech or eliminating a forum, as it would be unduly burdensome to investigate the merits of every complaint.[10] 

Some governments directly censor the internet by blocking certain websites or by flooding online platforms with pro-government content to drown out dissenting opinions.[11] The United States may be on the verge of censoring the internet, not through direct government censorship, but through collateral censorship.[12] Twitter, Inc. v. Taamneh may change the landscape of the internet, as this holding would not be limited to content related to terrorism—it would apply to all crimes.[13] As such, platforms would take down content regarding, for example, abortions and marijuana because in certain states marijuana use and abortion health care are crimes.[14]

A. General Speech

Platforms would likely foreclose discussions of controversial subject matter, including advocacy for rights and opportunities currently forbidden by law.[15] This would silence marginalized communities that use the internet as a powerful megaphone to effect lasting change, from the Black Lives Matter movement to the #MeToo campaign to the fight for LGBTQ+ rights.[16] This is the likely outcome as platforms could not use human review of all content due to the sheer volume of online content. Thus, they will err on the side of caution and remove most content.[17] However, automated tools cannot make complex assessments of the illegality of expression, which means that reliance on them will result in an arbitrary denial of lawful speech. Even if human review becomes possible, the platforms will remove speech they believe is legal due to the fear that a judge might disagree with their determination.[18]

B. Speech Regarding Terrorism

Even if the holding is narrowed to apply only to content “aiding and abetting” terrorism, platforms would still censor legal speech due to automated tools’ inability to comprehend the tonal and contextual elements of speech or to identify when speech is satire or published for reporting purposes.[19] Human rights and international legal observers reported that over-surveillance has primarily resulted in the removal of two categories of online speech: (1) the dissemination of news about terrorism and (2) speech in languages other than English.[20] While some platforms may use automated tools to remove all content about terrorism, “problematic content producers will overrun any undefended service, flooding it with material that other users don’t want.”[21]

III. Federalism Issue

Multiple states have together filed an amicus brief in support of the petitioner, arguing that the immunity Section 230 of Title 47 of the United States Code provides internet platforms displaces state law, although Congress did not explicitly write that.[22] To displace traditional spheres of state authority, Congress must “make its intention to do so ‘unmistakably clear in the language of [a] statute.’”[23] The language of Section 230 is clear, stating, “No cause of action may be brought and no liability may be imposed under any State or local law that is inconsistent with this section.”[24] The language embodies Congress’ obvious intention to preempt state law.[25] Without Section 230 state law preemption, platforms would have to not only remove speech regarding a right that is illegal in State A but also speech regarding a right that is legal in State B to ensure that it does not reach readers in State A.[26] 

Furthermore, preemption of state law has not displaced the state’s interests in protecting their citizens, as many states have enacted Anti-SLAPP laws acknowledging the chilling effect of frivolous lawsuits on constitutional speech.[27] There is increasing interest in passing a federal anti-SLAPP law.[28] While a federal anti-SLAPP law would provide social media platforms and users a shield from liability for their constitutional speech, the law would not dismiss these frivolous cases at the outset, while Section 230 does.[29]

IV. Conclusion

Some are characterizing a ruling in favor of the plaintiffs as just another area of law where plaintiffs would be able to sue the largest companies with the deepest pockets instead of the actual wrongdoers.[30] However, such a ruling would change the nature of the internet as we know it, silence constitutional speech, and make the United States another country where the internet is censored.[31]
