Admittedly that's a good point taken in isolation, but as you so eloquently put it, the amount of evidence available is not sufficient to make a statistically valid conclusion. "Suspicions" based on an assumption that something stands to reason are just that - opinion and conjecture.
The fact is that whether you can see the sidestick or not (and FWIW in the sim I could get a good idea of what the guy in the opposite seat was doing with the stick based on his posture), a combination of monitoring the aircraft's response plus timely and effective communication with your colleague in the opposite seat should nullify that potential problem.
