Really? So in your world, a writer's mistake is abuse, in the same way legal professionals using the copyright system to profit off of a small publishing businesses is?

It's like arguing that punitive fines for minor infractions, like jaywalking or speeding, would be justified because "you broke the law".

The outrageous maximum penalties ($100k/infringement), the nuance of fair use and copyright law, and the resulting cost of defending yourself means that the only solution if you don't have excellent in-house counsel is you have to settle for what they ask. It's legal extortion.
