Unless I misunderstand, I don't see the point: you can get this data with a RaspberryPi and an antenna available everywhere (and probably built in China).
Military aircraft that shouldn't be seen should just disable data transmission.

China knows that direct control is hard to achieve at scale. They know they can simply state their intentions and let the chilling effects take over. Banning Flightradar24 is a statement of intention that every one of their citizens can see.
Or, they want some parties to know what they’re doing, but not the citizenry.
Maybe this is overly paranoid but I don’t think we should underestimate the Chinese government.
I'm not sure about the relevant Chinese radio interception laws, but I think the difference between DIY receivers and Flightradar24 is that the website combines data from a great many listening stations across the world. You'd need one hell of an antenna to receive location data from a Chinese plane from all the way over in the EU or US, but these websites still allow us to see flight patterns above China.

Permanently disabling ADS-B on military aircraft sounds like a recipe for disaster.
