Why did the US just ban TikTok from government-issued cellphones?

The US government has banned TikTok on federal government-issued devices due to national security concerns over its China-based parent company, ByteDance. The US fears that the Chinese government may leverage TikTok to access those devices and US user data.

The ban means that, in about two months, federal government employees will be required to remove TikTok from their government-issued devices unless they are using the app for national security or law enforcement activities.

US security concerns about TikTok have existed for years. Donald Trump first attempted, unsuccessfully, to ban TikTok in 2020, but bipartisan efforts to regulate and rein in use of the app reached a fever pitch in 2022 after news outlets reported ByteDance employees were accessing US TikTok user information.

While other countries such as Indonesia have imposed temporary bans on TikTok, the biggest country that continues to prohibit the use of the app is India. India permanently banned TikTok along with more than 50 other Chinese apps after a deadly border dispute with China, citing national security concerns. National bans in other countries have not lasted more than, at most, a few months.

It depends on whom you ask. Several digital privacy and civil advocacy groups such as the Electronic Frontier Foundation (EFF) and Fight for the Future say while the potential for China to exploit access to TikTok is indeed concerning, other apps and services offer government entities, including in the US, similar access to user data.

The US has ramped up its efforts to address potential national security concerns from China over the last few years, including adding more China-based companies and entities to a commerce department blacklist limiting exports to those firms. The focus on TikTok is part of this larger campaign, but some groups warn that a ban on TikTok would lead to similar moves from China.
