I'd bet it would be more of shipped is king mindset. It's not so unprecedented that new categories of Chinese products dominate markets with incredibly insecure, stupid, and nearsighted implementations, and then buttons up one night and kicks out all open source development that benefited from lack of security.

Chinese phones, drones, action cams, robot vacuums, home security cams, smart bands, etc. all used to be insecure and vulnerable as hell. Not anymore.
