With Trump the issue is personal. He is angry that Tiktok teens sabotaged the Tulsa Rally. There is no chance of a Microsoft purchase mark my words.
Banning the app within the U.S. is actually very simple since the database and IT are all located within the U.S. They don’t even need to create a firewall to take it offline.
Tik Tok didn't hedge against this possibility, they didn't realize that if you give the US an inch they will take a mile.
What they should have done was build a headquarters in a European country and distributed the data around the world. Placing any valuable infrastructure in America is now a clear security hazard. If only the Chinese bourgeoisie weren't so lazy and desperate to integrate w/ America.
