Worse how? US users data is still for sale to anyone by US and non-US based data brokers. If the goal is to stop China getting user data, this ban fails to achieve that. It’s a political theater, since being against China is a popular position at the moment.
That’s the thing about privacy, you can’t ban one company, but still allow others collect the same data and share with anyone they want. If data is available for sale, anyone can buy it.
