TikTok CEO Shou Zi Chew is set to testify before Congress as the app faces mounting concerns over data privacy and security. The app, which has faced bipartisan national security concerns, has been criticised for its sophisticated algorithm and for posing a danger to young people. However, Chew is hoping to push back against those narratives and plans to underscore TikTok's commitment to safety, US user data security, and its transparency. The company's Chinese owners, ByteDance, have been told by the Biden administration to sell their shares to an American buyer or be exiled from the country. Despite TikTok's efforts to assuage policymakers, many remain unconvinced and Congress has already blocked it from federal devices. The ongoing US-China tensions add to TikTok's woes and have put its future in the US under serious threat. The big question is whether TikTok will survive if China scuttles ByteDance's sale of the app.
