You can certainly think whatever you like. Simply know there are people that work closely with CAC in China that share the same view.
Are
YOU a member of that group? If not, then what you claimed back on post 41 is as equally presumptuous as by those who you accused of being presumptuous. Of course, you can certainly think whatever you like.
In flight controls, it is not enough to have flight controls surfaces such as wings and stabilators. We need flight control laws. A 'push-pull' rod is a 'hard' law.

We can make the entire mechanical flight control system have variable output for every input. Or we can make it straight 1-1. We can make it so that a single input will produce multiple outputs, like a 'pitch-roll assembly'.
Horizontal Stabilizer Control System (Double Axis)
The control, stick grip movement is mechanically transferred to the left and right stabilizer servo cylinders through the pitch and roll command summing network, the feel assemblies, and the summing network.
Anyway we do it, the entire system, even mechanical, is governed by 'flight controls laws'.
Fly-by-wire flight control systems (FBW-FLCS) are much more dangerous in that we do not have the inherent conservativeness, or built-in restrictions, of mechanical linkages. Those laws are governed by softwares which in turn is affected by the sophistication of the electronics. Badly written flight controls laws can manifest themselves at any time during a maneuver. A set of flight control laws may not even have the engine thrust vectoring capability and leave that capability in the pilot's hands, making more work for the pilot.

It is not difficult to extrapolate from a stable airliner design to a jet fighter whose characteristics includes instability from when it was conceived on paper to see how much more complex the flight controls laws will be at the lower levels. Legend has it that the F-16's first flight was very unofficial in that the test was supposed to be a high speed run but the aircraft's aerodynamics lifted it off the ground. The pilot had no choice but to go along and eventually safely landed the aircraft. That was the first generation analog fly-by-wire FLCS.
The J-20's designers could be deliberately conservative for now. Or they may discover later that certain combinations of rules can send the aircraft into uncontrolled flight and exclude those combinations, making the aircraft less capable than its competitor. We do not know. So it is wise to put aside nationalist fervor and try to learn something.
