Weinstein is the director of Thiel capital and holds a PhD. I do not think he is a crackpot. He is butthurt over being victimized in academia for various reasons, and he is not alone in having such experienced. He is using his voice to call them out at the same time Publishing his work.

Regarding the theory. It is is impossible to me to analyze his work, because it is impenetrable. What is a two-tensor, gauge theory, I for one have absolutely no idea. I think this is an Achilles heel of his approach, he needs to convey meaning better. Or maybe that's just how a theory of everything is articulated.
