(Don't read if you don't want spoilers. Exit Through the Gift Shop is phenomenal and should be watched without knowing about this guy. Watch it, then read the Wikipedia article for yet another surprise.)
“Ghost Kitchens” have a more nefarious connotation than “delivery only” though because often it will be a single kitchen yet be advertised as many distinct restaurants. I saw one in one major city that was something like fifteen “different restaurants” operating from the same small space, which is sketchy.
But I think the person to whom you’re responding was relying more on the word “thousands” here. So given the connotation I think opening thousands of these things is pretty sketchy for some random YouTube personality with presumably no experience with restaurants to be opening simultaneously.
I don't believe the contract between him and VDC is out outlining the contractual obligations, SLAs, trademark and marketing issues etc.
