What we know about the TikTok ban
US TikTok ban pushes users to RedNote, sparking Mandarin learning spike.

The U.S. Supreme Court upheld a law forcing TikTok to shut down unless it divests its U.S. operations, leading to its distribution ban starting Sunday. Consequently, TikTok users are migrating to RedNote, a Chinese app now the No. 1 free app in the U.S., although this transition presents challenges for some.
As TikTok users adopt RedNote, there's been a significant uptick in Americans learning Mandarin on Duolingo, experiencing a 216% increase compared to last year. This surge particularly peaked in mid-January, coinciding with RedNote's rising adoption.
In a broader tech landscape, Mark Cuban shows interest in funding a TikTok alternative through Bluesky's AT Protocol. Additionally, other tech news highlights include Nintendo's new Switch, Sonos CEO's departure, and changes to various social media and AI platforms.
