It is most likely due to Denuvo being harder to crack because it is a widely hated DRM. Pirates probably want to crack it on principle.
I don't think most of the pirates actually care that much about whether people download their releases. They just want the credit within the scene of cracking something that's hard to crack or leaking something before street date. For-profit pirates would be an exception to this but I doubt they're very prevalent because most people are pirating to avoid paying.
Denuvo is also an exception to piracy as a service problem being solved because it is widely hated even by non-pirates. If pirates rendered it ineffective, companies would not be using it for their games but preventing piracy is worth the backlash as far as they're concerned.
