I'd be more concerned if the software updates and information were going to China as opposed to wherever Tesla operates. I have more confidence in Tesla than in a Chinese state or Chinese Communist Party-dominated business. I don't know if Tesla has Chinese Communist Party branches in its manufacturing facilities, but my main concern is the potential access of Chinese intelligence to the data.
Obviously, Tesla, Google, and all these companies gather a terrific amount of data that is used by them, but they are not regimes that are preparing to engage in a hostile confrontation with the west over, say, Taiwan or the South China Sea, and would use the potential of EVs in our country to serve their geostrategic aims.
