Apple and Google removed the app after the Supreme Court upheld a law prohibiting firms from doing business with TikTok as long as it is controlled by China-based ByteDance.

The law requires TikTok's Chinese parent company, ByteDance, to sell its U.S. assets in order to continue operating in the U.S. While the law only mandated that ByteDance remove TikTok from app stores in the U.S. if it failed to meet the sale deadline, company executives decided to shut down the app entirely.
