I was thinking delusional, but the thing is that their thing does work - it’s just not their work. They repackaged CADO-NFS (a well-respected factoring program) and pretended that they’d invented a new factoring algorithm. It’s actually simple plagiarism.

Now, what I could believe is that there’s a massively deluded guy at the top, and a bunch of underlings who are desperately trying to enact his crazy vision. But it’s pretty hard to ignore the evidence that this is a scam.
