I sent that machines for him for free.
That is my product, with my customizations, my work. And yes, there is proprietary customizations, but I don’t care, they will fail and the market deserves to know.
Unfortunately, that company looks like a fraud, rebranding software and saying they developed without give the proper credits.
What they did with Bitcoinize Machine, is another proof of their bad behavior.
