Russian and Chinese aircraft – obsession in this forum ??

I have noticed in the last months that this forum is imho biased in favor of Russian and Chinese planes.

Western planes on the other hand a regularly criticised and seen as failures or outdated. Funny enough we know much more about all western fighters. Testing reports, reports from accounting offices, senat hearings, whatever are available to confirm if the aircraft is fullfilling the promised specifications or not.

We have no comparable sources for eastern planes. Yet all specifications given by the manufactures (Russia) or rumored (China) are widely believed in here.

Why is that the case ??
