There’s the other angle as well. DRM itself could be considered immoral and evil in a post-collapse world. Suddenly, when the bombs go off, a lot of people’s photos, home movies, survival guides, libraries all stop working. The old law enforcing the DRM may be gone, but the old DRM is still a very inconvenient or possibly impossible obstacle to get to everything that was ostensibly yours. Back in the good old days when Amazon still existed, instead of being a radioactive pile of rubble.
The bombs didn’t just physically erase families. Now that all our photo albums are on vaporized encrypted servers, even the memory of those families are gone.
