While still a small percentage, the amount of people who refuse to buy Denuvo infested games is probably growing, so they might wanna minimise the risk of companies not implementing it. The issue is that the kind of people who would avoid such games aren’t gonna care about your attempts to improve your deservedly shitty image lol.
They know that people not caring or being aware of them isn’t going to cut it, people who are aware of it and its impacts don’t want it. And since it is publicly disclosed that it’s there in the game, and there are lists and curators to make that more apparent, not knowing isn’t likely to be something to last for long.
So it’s only natural they’d want to try and improve their image, though this little stunt definitely did not help them.
