It's not banned. It was never banned. The whole thing was a great big farce. Biden said he wouldn't enforce it, then TikTok ignored that, and went through the performative exercise of "banning" itself, to drum up a bunch of press, panic and outrage, especially amongst young people. Then they used the opportunity to kiss up to Trump by pushing the false narrative that he somehow "saved" TikTok.
The whole point is that Trump gets to force TikTok to sell to Elon Musk, or some other American billionaire, and then it goes right back to doing what it was doing before... farming personal information and metadata for sale to the highest bidder and other forms of internet/media manipulation. Its just another scam... with a side order of extortion/robbery.
Meet the new boss, same as the old boss.
