What do you mean by “is it fair? (Is it supposed to be?)”?
Yeah, I hear you. People who labor with the expectation that they will be paid a certain way have every right to feel icky to when someone flips that expectation. Unethical even. Though maybe nobody would feel icky about freely sharing I’d that were just what everyone expected while making the art. In fact, making the art might be even more of an act of love or creativity knowing that once you share the 0s and 1s, they fly out into the world to live on their own.
On the other hand, it feels very icky to me to say that we are gunna make SURE people don’t use the 0s and 1s on their own computers in their homes in ways we don’t like. Like how is that actually done… well people show up and use the real threat of overwhelming physical force to MAKE people to behave in a certain way with the 0s and 1s. Gross. Not 100% sure but I think that’s the only fundamentally unethical part of this.
On the last point, who would pay anyone but you in a DRM-free world? Maybe a few cents for the copy of the 1s and 0s, but then they might send you much more in appreciation for the original work. The first person may have been their doorway into your art, but you are and always will be the creator of it.
