I think if someone actually had government handlers asking them to do this, most of those people wouldn't blab about it to their school chums. But there's a subset of people with grandiose delusions / general behavior problems who feel a compulsion to tell everyone about their grand plans/machinations to become rich and powerful.
It most likely wasn't a Handler/MSS type espionage.
It was most likely trying to grab IP to found a domestic competitor, and raise a Seed round from local government accelerators like those Beijing and Hangzhou have.
I think you are underestimating how tough it would be to be playing James Bond and not tell anyone.
You wouldn't have to be a delusional braggart to want to tell a friend this. Most spies are not going to be as much of a compartmentalized lunatic like Robert Hanssen or someone at that level.
