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.
> Military aircraft that shouldn't be seen should just disable data transmission.
Permanently disabling ADS-B on military aircraft sounds like a recipe for disaster.
