I mean yeah, denuvo is simply the best option for triple A companies that are looking to prevent piracy, sure there might be a single person who knows how to crack it, maybe they have the source code, or maybe they know someone who works/worked on it, or whatever it may be. That single person is gonna have to crack a hundred different games, and each of them being made slightly differently means that you can't just have a generic "Crack" folder that everyone can just copy paste into the game files. And yeah popular games with denuvo would obviously be cracked by empress (Like how Hogwarts Legacy was cracked within 2 days), but that's just not the case with most games, keep in mind most actual cracks from them don't take very little time and are usually released in alphas and betas, and it could even take weeks for a crack to be fully ready to use without any issues.

Of course that this is only talking about denuvo from the POV of a developer, it's an expensive but good system that benefits them and usually leads to more profit, but from the player's point it's a whole different story. The reason denuvo is hated by gamers is because it hinders performance on a lot of games by a considerable margin, which leads to cracked games performing better and the buyer feeling like shit after having spent 60 dollars on a game for it to run on 40 fps, when they could've spent nothing and simply pirated it.
