i think tik tok themselves decided to go down in order to pressure trump to sort it quickly, a bit of a risky strategy given trump, he is only recently a tik tok apologee but does he want to be seen to cave into a chinese company pressure tactics
TikTok said it is "in the process of restoring its service" in the US, adding it will work with President-elect Donald Trump on a long-term solution that keeps the social media app in the United States.
With Trump money talks...and Zucker and Musty are getting cosy with him. I'd guess they don't want any controls on social media, and they aren't too far from ticktox. Trump isn't going to fall out with those guys.
