In copyright situations, it comes down to how much the copyright owner has lost in income or if their public integrity has suffered. It's up to the owner to decide to go after the "plagiarist," but if the cost of doing that outweighs the ability to recover lost income is the main factor. One thing most people don't realize is you can win a case, and if you are entitled to compensation, collecting it is a whole nother thing entirely. OJ, "the killer" Simpson, hasn't paid the Goldmans for killing their daughter yet.
Companies like Daz know the cost-benefit ratio is on their side. Yeah, some of their assets are stolen, but that is the cost of advertising their product. Daz is big because we see its products everywhere. And if the profit margin drops, you can bet they have a strategy for that. That's what free refills are at fast food places are, advertising.
