The Tik Tok ban is just theater
As the title says, just theater. Once Trump is in office it will be available again, giving the chinese three months time to sell to the americans, Musk or some other billionaire will buy it and it will continue to operate in the USA.
Trump will be the saviour of free speech and the hero of the masses while america now has a new powerful surveilance tool. If the chinese don't bend the knee they will probably establish Musk's X with new features as the new Tik Tok.
