You don't have an automatic right to compensation or audience for your work. Your right is that others can't take your work without your permission--i.e. that they don't own your text just because they can read it. If you have no rights over your text, then only the man with the printing press wins. When you do have those rights, you can trade them for compensation, audience, etc. and that's your choice, not theirs.

As it is, the companies that get harmed by piracy of the kind that DRM prevents are parasites on society, and the notion that the deal that they force on the rest of us though their position of economic dominance is some kind of "social contract" is laughable.

My brother in Christ, you work for a two trillion dollar company built on these same rights.
