Denuvo definitely does attempt to hire from the scene. It's less that they necessarily need those specific peoples' skills, but rather because there are so few people who can crack Denuvo, so hiring a single such person dramatically reduces the number of people out there cracking your games. The most famous example being Empress, who was the only person in the world cracking Denuvo for a few years. I'm sure Denuvo would have loved to hire her, if only to stop her from releasing cracks.
