Nah, they'll sell. It would be foolish for them to admit it publicly, that would drive down the price. They'd also lose influence in the American media landscape if they killed TikTok. Finally, they're fighting this law in the courts, and admitting they'd sell if forced too would be weakening their position. It's not like selling would really hamper CCP control all that much, they'd just send texts to people's personal phones when they need something instead of sending official emails.
