The state’s flagship university calls TikTok – operated in the U.S. by a subsidiary of a China-based company – a “national security concern” and discourages the campus community from using the app on their personal devices. It’s also going further, banning any future academic research projects that involve accessing TikTok. Officials at other Florida universities say they are considering similar action against TikTok, but none has officially followed UF’s lead yet. TikTok says it’s trying to convince federal national security experts that its app is safe.
