Your first link, there is truth to it, the most obscure and small stuff won't be pirated. Does that matter? I don't think anyone is only looking to defend things that are that obscure. Anything with even a middling number of people interested has it's DRM blasted through very quickly as far as I see.
Your second point, Denouvo is for video games and is a very different ballpark - it turns out storing code to lock things down is a lot easier in an executable vs in a video. DRM is certainly more effective in games (although the evidence is it causes way more problems for legitimate users, and Humble Bundle et al have proven that users prefer legitimate options when they are easy and affordable).
