TikTok: Lip-Sync App or National Security Threat?

TikTok, once a niche lip-sync app called Musical.ly, now sits on 170 million U.S. devices, shaping how Americans entertain themselves, get news, and express personal views. As its influence grew, the app became entangled in U.S.-China tensions and centralized efforts to ban it or force a domestic sale in the name of national security.

In 2024, Congress passed the “Protecting Americans from Foreign Adversary Controlled Applications Act,” requiring TikTok’s China-based parent company, ByteDance, to sell off its United States operations or face a nationwide ban. After a prolonged series of federal legal disputes regarding the constitutionality of the divest-or-ban law, the Supreme Court ruled in 2025 that Congress’s “national security” rationale justified the mandate. Since then, TikTok has remained at the center of legal uncertainty and scrutiny.

American investors want to strip ByteDance of its extensive control over the platform, aiming to garner over 80% of the restructured entity and leave the core platform under 20% ownership to comply with previous federal regulations.

At the center of this debate there are two main concerns: foreign data access and opaque algorithmic influence. TikTok collects extensive behavioral information on Americans based on what they watch. It's curated For You Page seems to always know the last conversation you had. Similar to other social media platforms, its algorithms “choose” what to show certain demographics based on retained data. What distinguishes TikTok is its compliance with China’s National Intelligence Law and Data Security Law, which can compel cooperation with state authorities. This is paired with TikTok’s opaque algorithm, which Washington fears could subtly—or overtly—amplify or suppress political narratives.

Policymakers note these concerns are not baseless. China has been tied to significant cyber intrusions, including breaches of federal personnel records and probing of U.S. critical infrastructure. Critics argue that this regulation is purely preemptive, as there is no public evidence that China has accessed, collected, or misused user data. While imminent harm was not clearly present, the Supreme Court deferred to Congress’s judgment and concluded that a present, credible national security risk is enough to justify federal intervention.

Civil liberties organizations have a different view. Groups including the American Civil Liberties Union (ACLU), Electronic Frontier Foundation (EFF), and the Knight First Amendment Institute at Columbia University argue that TikTok is not merely an app but a major vessel of modern expression. A ban or forced restructuring raises critical First Amendment concerns and could set a dangerous precedent for restricting or disfavoring foreign-owned platforms.

Regardless, the deeper issue is that TikTok has become a smokescreen for the United States’ lack of a comprehensive federal data privacy law. Numerous U.S. companies collect similar or greater volumes of data, and data brokers can legally sell sensitive information with minimal oversight. Thus, if a foreign government sought to purchase sensitive American profiles, it could do so commercially—and legally—accumulating vastly more confidential data than TikTok could ever provide. By singling out one China-owned company, the approach does little to address systemic vulnerabilities and further blurs the lines between political and legal influence.

A sustainable policy response must move beyond single-platform bans. Federal policy should apply to all platforms (foreign and domestic), feature risk-based oversight that corresponds with a platform’s power and influence and use transparent national security tools that require less restrictive alternatives.

TikTok’s future remains uncertain, but the broader political challenge is clear: the United States must redefine proper national security and scalable platform governance while protecting the civil liberties essential to a digital era in which online platforms like TikTok shape culture, politics, and global influence.
