Because not having a DRM solution makes shareholders nervous. So a pointless system that actively makes the game worse, is a positive still.

Because they weren't being cracked AT ALL for the better part of a decade. There has been an entire generation of crackers failing to crack Denuvo until the start of 2026, and I'm pretty sure that the actual cracks being released today would not be possible without the Hypervisor workaround being developed first.

Most games make the largest amount during the first week or two, so if it takes longer then that for someone to crack it, then it was probably worth it to the publishers. I don’t follow all the denovo news, so maybe with the new hypervisor stuff this is a moot point, but most games haven’t been cracked immediately.
