Looks like both Bytedance and Musical.ly are Cayman islands, so I'm not sure how the US has any say in what they do, though I understand the spirit is "do what we want or lose the US (and possibly the world) market". I don't know how anything the US does can affect what two companies in a different country decide to do between them, legally speaking. The executive order sounds weird to me. Also, I don't understand how they can block a sale three years later. What's the time frame on that? Why not ten years later? A hundred?
