His criticism that the paper is speculation is spot on. Many of the references don't support the claims they are cited for. It's fascinating to me that you want to argue the poster's standing to make a criticism more than you want to actually discuss the content of the paper.
Its a particularly weird criticism given that Danny is a lawyer and has experience in the CS research community. He is especially well suited to address a criticism that the authors are trying to trick people into thinking their work is a scientific paper, which is plainly a ridiculous criticism.
