They're sovereign.
American tech companies. American national security organs cannot touch them, cannot put the hurt on them. They are independent and there is nothing Meta, Google, Oracle, etc can do to them. Look at Europe, look at the rest of the world on Facebook and Oracle products with a big gun right at their temple held in the CIA's hand if they do something the US doesn't like. China doesn't have that gun at its head and because of that China can be truly sovereign from the US.
