Technically would be correct to say its being split into TikTok US and TikTok Rest of World , probably why one of their new ToS includes geolocating the end user for user segmentation. Since i dont think they are going to split the app - probably keep using the same published one.

It seems like what this will basically entail is a US algorithm and moderation system, while the core app remains with ByteDance.

> The Joint Venture will secure U.S. apps through software assurance protocols, and review and validate source code on an ongoing basis, assisted by its Trusted Security Partner, Oracle.

So the new team will be in charge of content moderation, training, and "review and validat[ion]" of source code. Not actually a new app.
