he's giving people software to spy on their spouses on other people's computers (the boyfriends, the companies, the schools, etc).
But he is using computers operated by him to transmit illegally obtained information.

The Loverspy program, disguised as an electronic greeting card showing images of puppies and flowers, was sent as an e-mail. When it was executed, it would begin recording victims' e-mail messages and the Web sites they visited, prosecutors said. The information would be transmitted to computers operated by Perez-Melara and relayed to customers, authorities said.
