I mean, I'm not sure what China expects the US to do with a company whose very existence and arguably their success in the market is due to corporate espionage. China can reframe and project all they want, but they will always have someone keeping tabs on the cookie jar and they only have themselves to blame.
The entire US is built on corporate espionage of British secrets.
Corporate espionage is literally the way countries progress when disadvantaged. That doesn't mean that the less developed country can't criticize the more developed country for corporate espionage.
If China wants to base their economy on trade secrets stolen by state-backed hacking, then feel free to enjoy better state backed hacking, courtesy of the American Military Industrial Complex Uncle Sam!
Long before the United States began accusing other countries of stealing ideas, the U.S. government encouraged intellectual piracy to catch up with England’s technological advances.
That not an argument to support China using stolen tech, though. Just because US did a bad thing, doesn't make it ok for China to do so.
The argument is that they should expect to be hacked when using tech stolen from other countries. By pointing out US also steal technologies, you're only arguing that the US should also expect to be hacked, an idea no one was arguing against. You're basically arguing against a point that hasn't been brought up, yet.
