Wouldn't regulating data privacy just shift the banning to business behaviors instead of consumer behaviors? It's still banning of choice to what the government says.
(Said with tongue in cheek. Help explain where the reasoning is wrong, though. The majority of people would rather get free apps with heavy surveillance attached than pay for anything in money or inconvenience, why is Tiktok different than everyone who sells the data to brokers who then sell it to everyone?)
