There is an element of this that involves the responsibility of governments to protect their people's data from becoming weaponized against them. I haven't been able to ascertain all the details of the TikTok debacle, but IMHO the key thing government should be doing here is ensuring that data remains within the country from which it originated. These sorts of data and privacy concerns are quite reasonable. Robbing brilliant ideas from other countries is not.
