The federal law banning TikTok has revealed a major schism among American tech companies: Some are willing to flout the law — and some, including Apple and Google, are not.

The app has repeatedly name checked the president-elect in pop-up messages and statements, as it navigates a ban in the United States unless it is sold to a non-Chinese owner.

The popular video app stopped working shortly before a federal law barring U.S. companies from hosting or distributing TikTok was set to take effect on Sunday.

TikTok is set to be blocked in the U.S. after the Supreme Court upheld a law that effectively bans the app. TikTok, a Chinese-owned social media platform, has drawn scrutiny from lawmakers for its national security risks and its ties to China.

After a decisive loss at the Supreme Court, the app is set to be blocked in the U.S. starting Sunday, ending its streak of Houdini-like escapes.

With the court signaling it will release a decision on Friday, lobbyists for the app pushed lawmakers to shift course.

The move is under discussion as the Chinese-owned app faces a Sunday deadline to find a new buyer or shut down in the United States.

Shou Chew will join tech moguls like Mark Zuckerberg and Elon Musk at President-elect Donald J. Trump’s inauguration as the fate of the app hangs in the balance.

Ahead of a Supreme Court ruling, they are mocking U.S. national security concerns about the Chinese-owned app.

The company is awaiting a decision over the constitutionality of a new law that aims to force a sale of the app to a non-Chinese owner under the threat of a ban.

The plaintiffs include a Texas rancher and a hip-hop artist who say banning the app violates their First Amendment rights. TikTok is paying their legal bills.

Plus, goodbye to a hairy “Shrek” icon.
