Maybe that's because these sob stories were already accounted for by the _original_ copyright length of 28 years? The vast majority of DRM is protecting some corporation's right to profit off of the work of content creators almost indefinitely.
I'm not talking about copyright law, I'm talking about DRM. Go look at the videogame industry and denuvo. They use it because it's hard to crack during the initial sales window, once it gets cracked usually after a couple months they patch it out and don't bother to replace it because its job is done.
