He has consistently to this point not been willing to share information or control of his product with any more investors.
I asses that to mean that the fewer people he has on board, the greater hit take will be (or loss if it flops).
Publicity and hype for his product he wants. Investors on his wagon, not so much. Bigger steak for him and if it crashes less damage to his reputation.
I think he is sincere ( even if this pans out like bubble memory in the 1980s).
He’s a fine charlatan I’ll give him that.
