That's an extremely bold claim. There are many games which are successful and don't use Denuvo. In fact I'm quite sure there are more successful games that don't use Denuvo, then those which use it - so I don't believe that "whenever [I'm] playing and enjoying a game" it was "most likely" created thanks to Denuvo.
And then there are people like me who simply refuse to play any game which uses Denuvo. There are thousands of excellent games out there, why should I waste time on those which treat me as a thief?
