China is beyond self-serving. It's mindset is confrontational, it's history is replete with instances of occupation of other peoples lands (Mongolia, Tibet, etc.).
It is politically very unstable, so it has to periodically create crises, to whip up nationalism and keep it's population in control.
Chinese infiltration takes a myriad of forms and data collection is one of the biggest.
And those apps form a basis for click-of-the-button hacking.
And ordinary users will find it very very difficult to determine if an app is Chinese made or not.
And the Chinese govt. will have it's fingers in everyone of them, one way or the other.
What I do worry now is that since China has been exposed, it will resort to even elaborate deceptive methods to hide itself and it's infiltration.
China is not to be trusted.
