The article mentions yomali out of Malta. Yomali's just an ecommerce, billing and hosting site doing payment processing for the people selling these guides. Much as Google and AWS host services for numerous questionable companies.

Malta has some weird tax advantage apparently because a lot of ecommerce goes out of there. Also Cyprus.

Yomali's owned by an Israel guy who says his name is Mike Peters. ( https://www.entrepreneur.com/article/326673 )

It's likely he and his company have little to do with these ebooks other than handling payment processing for them along with many other small companies.

Malta appears to be somewhere you can get an EU banking license without quite so much scrutiny and oversight as some of the larger places. Coincidentally quite a few cryptocurrency-related organisations have moved their HQ there...

Malta is also a location where a lot of questionable cryptocurrency related firms have chosen to incorporate, and get bank accounts.
