There is no one outside the US with both the tech skills and the cash to buy something the size of TikTok. Heck, there are very few in the US (adding the third requirement of no antitrust concerns).

If TikTok were a Canadian, British, French, German, Korean, Japanese, or Taiwanese company, the US government wouldn't have intervened in the first place.

But naturally they don’t want to offend China so why take the risk when you can try to play both sides as long as possible?
