Well why have drm then, if it's still and issue with or without? Especially as a large majority of your paying customers find it annoying.
I'm skeptical of the idea that it's binary. Can they pirate your product? If yes, your efforts were in vain. It's not a logic I really see people applying to any other crime. Can people break into your house if they want to? If yes, don't buy locks.
I can understand, appreciate, and sympathize with the idea that it's annoying to customers, however. And that's a good argument against DRM. But the argument that DRM isn't perfect, therefore it does nothing, strikes me as suspect.
