Yes, you touch on something that is key to the past few years of soft disclosure: why are highly cleared people like Grusch, Gallaudet, Nell, and so many others putting themselves in such a delicate position? I have not been able to come up with a solid plausible explanation, other than they genuinely believe what they say, bizarre as it sounds.
And what sort of evidence does it take for people like that to believe things like that? I presume it takes more than blurry dots moving against a dark background. Hopefully future data releases will give us something that answers that question.
