annoying

How so? You usually don’t even notice it’s there.

unnecessary

True, but I just don’t think most people care about that a lot. Because if you look closely at how much shit is running on your PC at any given time, denuvo is probably just a small drop of water in the atlantic ocean.

drain on resources

That has mostly been debunked by today.

Personally I avoid it also because until recently it was borderline uncrackable and thus prevented me from keeping my games through posterity.

That is the only reason I can absolutely understand. Not “owning” your game is a shitty feeling, but we also lost that battle like 25 years ago with steam. I think it’s silly to be mad about denuvo but still use steam for your games if DRM is such a problem.
