Suicidal naïveté
Nothing happens in China without the concurrence of the PLA, who own a share of most industries. To quote an economist acquaintance, the PRC is the first economically successful, technological, totalitarian regime. It’s beyond implausible that they are not using their tech kit to gather intelligence world-wide. By all means read Ken Thompson’s Turing Award paper mentioned above. Would be nice to see some studies of who’s phoning home.
