For the average person? Likely not. China is not going to monetize how many times you play a tswift song or stop into kfc and harrass you with ads/etc.
For the country as a whole? Maybe worse, as those total domestic patterns may be dangerous in aggregate.
Still, its all horse and pony show. The US data brokers will gladly sell unlimited data to China. All Chinese cars would do is cut out of the middleman by collecting the data themselves.
The real, correct action is too outlaw data harvesting period, but there is too much of our economy based on it, so here we are, talking about individual app bans for chinese social media like tiktok and chinese car data harvesting instead of all social media or all car data harvesting.
EVs are not spies. China gets more intel from former government employees than they do from people's cell phones or TikTok. Indeed is used for spying more than anything because people advertise their experience and makes it super easy for spies to find who to contact.
You don't see spies sneaking around at night breaking into cars to access info stored on the cars computer. When was the last hack of legacy auto servers with telemetry data?
