Something doesn't add up about the descriptions of the assets of the Sole owner & operator of the business. How did one person amass the data of millions while operating alone with so few assets (two HP Pavilion desktop computers)? Feels like there are assets hidden away, or that the data was being accumulated though some other company. It doesn't feel like the company was operating significant cloud infra.
