Moral opposition to the concept of DRM perhaps. For me in fact it's that DRM is such a massive pain in the ass that I usually buy the game and then pirate a copy that I can actually play without any storefront/UPlay/EPIC horseshit.
For this reason I tend to prefer buying my games from GOG, which sells all its games DRM-free.
I do value the work game developers put in these games and I buy all of them, but I like having the peace of mind that if something happens to my purchases down the road I could run a cracked executable later on.
It's quite common when a developer updates a game to remove Denuvo, or when an official Denuvo-free executable is accidentally leaked (as appears to be surprisingly typical), but I don't think it's that common for cracks.
Cracks generally do the absolute minimum to get a game to run, which often means leaving neutered but still performance-intensive DRM in place. Once a game works, I've never seen anyone take a second pass to improve performance. (Games that actually crash are of course a different matter.)
IMO, this is again an indicator of the scene's priorities.
I dunno, I suppose a tiny minority is all you need, so maybe that's it...
Plus there's a huge number of people who go through a piracy 'phase'. Usually to get games when they're a teen with no cash. Most of the games they love are purchased once they've matured with a stable income.
Speaking from experience!
We were fortunate to benefit from a program meant to help get lower income families access to computers and the internet, in the early 2000's, so piracy opened up entertainment options far more diverse than the TV channels we could get over the air. On top of games, I remember burning music CD's for my friends and family. Hell, I remember long hours fiddling with the concept of transcoding and burning VCD's (basically a DVD, but on a CD) for my family to watch.
