I was accused of the same thing, being a part of AMD or some AMD affiliate was the accusation.
I think that those who make claims need to back them up with evidence. Those who level accusations absent evidence should get a ban from the forums.
It is nearly impossible to disprove a claim that is absent evidence. The mod will ask you "Do you work for AMD"... And the only thing you can respond is "No". You can't prove that you don't. What are you going to do? Send in a pay stub from your employer or a copy of your contract?
Absurd witch hunts by folks who wish to silence opinions they disagree with.
