Basically everyone is simply hallucinating, whenever they share any experiences, without “proof”, or any measurements to back up their experiences.
I don't think they believe people's experiences are hallucinations. It seems pretty clear to me that they believe there is no place for subjective opinion when evaluating equipment on an objective basis as it is factually empty on an individual basis. One can never reach a logical, rational, supportable conclusion via 3rd party opinion. If one wants to share personal opinion, that is not the site for it.
There is perhaps something to be said for sticking to objectivity- here, in this very thread for example, you can see people called idiots, deaf, and liars simply because they have expressed a subjective opinion that that the op disagreed with, based on his own subjective opinion. Ironic, isn't it?
