TikTok, a rapidly growing social media giant, has faced severe congressional and legal scrutiny in the United States due to its connections with the Chinese government. This scrutiny led to the implementation of The Protecting Americans From Foreign Adversary Controlled Applications Act, which initiated complex legal debates over the balance of national security justifications and the First Amendment interests of Americans. Analyzing previous arguments presented to and provided by the Supreme Court in their decision to uphold the Act’s constitutionality, I argue that the national security justifications utilized by the Court provided inadequate consideration of the impact on American users’ First Amendment rights. This legal analysis and its findings exemplify the potential future restrictions on foreign-based social media and communications platforms within the United States in the name of national security. The future of TikTok in the US remains uncertain, and this pivotal decision highlights the Supreme Court’s readiness to prioritize national security concerns over constitutional freedoms, signaling a new era of digital governance and opening the doors to potential future global censorship.
