In an ideal world, the DC agreement is substantially fair: it gives independent authors the chance to receive better exposure, access to limitless amounts of incredibly talented professionals to help them polish their work, and a steady flow of income - in exchange for exclusivity, a chunk of money, and a certain regard for DC's investment.
But at some point, greed kicks in. DC "forget" to send a royalty check or three. They start making plans to make more and more money (games! movies!), for which original authors are just annoying roadblocks. And it all goes to hell.
It's so sad, because it's all so unnecessary.
