Only gamers, Redditors, and unhinged liberals actually give a shit. The popularity of TikTok shows that most really don't care as long as the treats are good. That's why the US has to try and ban it to keep them from growing.
Does TikTok give info to the Chinese government at all though? Its American data is stored in data centers in the US (not China) and it uses Oracle for cloud stuff. If anything, it's leaking data to the American government.
They store info from people who sign up to be a monetized creator, that's good to know. Though if the US has a problem with it, then that's the fault of their Committee on Foreign Investment who negotiated that deal in the first place.
