With President-elect Trump adding uncertainty around whether a TikTok ban will go into effect, the focus is now turning to companies like Google and Apple.

Apple and Google removed TikTok from their app stores Saturday, complying with a law requiring China's ByteDance to divest the social app or see it face an effective ban in the U.S.

Look at Huawei – the Chinese telecoms giant – and Kaspersky – the popular Russian anti-virus maker. Both accused by the US of posing a risk of spying by the US and both eventually banned or restricted not just in the US but in dozens more countries.

The U.S. Supreme Court officially upheld the law to ban the TikTok social media app on Friday. The case has become a pivotal moment in the debate over free speech and national security, following President Joe Biden's new act to ban TikTok in the U.

U.S. officials have long feared that the widely popular short-form video app could be used as a vehicle for espionage.
