Could you address specifically which parts you are referring to? I speed-read through it and didn't notice anything that wasn't established fact, especially the DARPA bits.
We need an analogue of Godwin's law for the use of the phrase "conspiracy theory." It's a term used by naive establishmentarians to discredit any attempt to dig into the darker reaches of politics, even when the stuff being discussed is well documented and consistent with historical fact.
I rather think it was a play on the word "antidisestablishmentarian" which technically would be one who is opposed to the disestablishment of the Anglican church as the official church of those lands governed by the queen of
England. [1]
In this case an establismentarian would be presumed to be anyone who favors the current order of things; whether it be a democracy, a cryptocracy or a kakistocracy.
