It's the only big non-US owned social media. They hate that because it's much harder to control. It's not even about the profits to be had, tiktok gets more eyeballs and especially it gets the young people's attention and has more public thrusts than all of the MSM combined and because Bytedance doesn't hate their HQ in the US the US government, intelligence or special interests, can't just call them and strong arm them into censoring whatever talking point that they don't like currently. It's not much more complex than that. "Chinese spying on Americans" is just projection of what all the other platforms do.

Those who push this will not be happy no matter what Tiktok does or whatever concessions it makes. They already hold american data in American and EU data in the EU for example. Did that stop the "muh CCP influence" propaganda? Well, no... Their main goal would be to get Bytedance to sell the platform to Americans, atleast the american business. I guess they would rather let it get banned and sacrifice American or even all the western markets than to let that happen. It would be a loss to them either way.
