To be fair denuvo is really effective.

It usually takes a long ass time for denuvo games to get cracked if at all.

Last I checked there were only two people cracking denuvo, one who only likes football games and one really crazy lady.

Also the lack of piracy is most important for publishers around launch and that's reflected in denuvo's pricing which IIRC increases substantially after a year or two (this is a fairly recent change)

So more games have started to remove Denuvo after a while after launch.

Before they changed it, I believe the publishers got to keep Denuvo at no extra cost if they didn't change the game or something but now it gets more expensive the further from launch you go
