TikTok stores data on US soil. That's part of the deal brokered by the self-claimed best deal maker Mr. Trump.
If there is unauthorized data access from inside China, then that's an issue to be investigated.
So, where is the evidence of the large-scale data access from inside China to TikTok data?
> “Everything is seen in China,” said a member of TikTok’s Trust and Safety department in a September 2021 meeting. In another September meeting, a director referred to one Beijing-based engineer as a “Master Admin” who “has access to everything.” (While many employees introduced themselves by name and title in the recordings, BuzzFeed News is not naming anyone to protect their privacy.)
A US companies' internal employees were conflated to China? And who the hell allows TikTok to operate in US in the first place. If someone working at MSFT has access to MSFT's China user data, is that a problem?
