TikTok, with over a billion global users, faces increasing scrutiny over national security concerns, particularly in the U.S. and India. Critics worry that its Chinese ownership could allow the Chinese government to access user data, prompting calls for a ban. In response, TikTok has taken steps to increase transparency, including establishing data centers in the U.S. and launching "Project Texas" to secure American data. Despite these efforts, the U.S. government banned TikTok on federal devices in 2024, and a full ban remains under consideration. Supporters argue such actions infringe on free speech, while others see them as part of broader U.S.-China geopolitical rivalry. As the platform navigates regulatory pressures, its future depends on balancing privacy concerns with its cultural and business influence, highlighting the complex intersection of digital governance, security, and personal freedoms.
