These Chinese companies use the data in ways that enable scamming of millions of people and businesses per year. The sheer amount of cybercrime that comes out of China and NK is crazy, its genuinely a threat to average people.
Authoritorian state with highly controlled internet and financial system isnt exactly a good place for running criminal enterprises.
There just 1.4 billions people in a country and many of them well educated and tech-savvy, so it obvious there just more scammers in total. But I doubt higher percent of population doing scams than average in the world.
OP was talking about about China, no one here is using NK AI models or software stacks, so your comment is not only factually wrong, it’s plain fear mongering propaganda.
