Game dev here, I work for a large studio that started using Denuvo recently. I'm neutral on piracy and pirate TV shows a lot, so don't give me a hard time, certainly not here to judge.
I do want to explain what happened here, Denuvo Software Solutions offers a guarantee, if your Denuvo game is cracked within a certain time (3 months is normal), you do not have to pay for Denuvo. Part of claiming the refund is you must remove Denuvo from your game.
One of the reasons why the management of my company used it, they think it is a no lose situation. I personally think it is more nuanced, Denuvo is expensive and my management think we lose a fortune to piracy because the industry inflates the figures as I think most of you all know. My management buy in to the inflated figures and Denuvo Software Solutions of course uses them also.
Obviously I'm just a developer so not aware of the numbers but eventually I'll find out if Denuvo helped, my educated guess is that it won't help improve sales figures as much as the management hope. To protect a AAA game, Denuvo charge high 7 figure sums.
