TokTok isn't owned by China. It was founded in Singapore, it's organized in the Caymans, and its main offices are in California. China owns a chunk of a different Bytedance subsidiary, bc they *did* outlaw TikTok.
I've never seen a TikTok vid deleted for critiquing China. Right now, though, the algorithm rewards critiquing Israel, as that's what gets engagement. (People leaving comments is engagement, no matter what the comments say.)
