App used by 170m people in US will become unavailable unless outgoing president directs DoJ not to enforce law, company says

TikTok says it “will be forced to go dark on January 19” in the United States unless the Biden administration assures service providers that it will not enforce a law banning the Chinese-owned social media app that was upheld by the US supreme court on Friday.

The nine justices voted unanimously in a decision that sides with the majority of the US Congress and the US Department of Justice that the hugely popular social media app is a threat to US national security.
