It is completely reasonable for these industries to seek laws that will protect their valuable intellectual property and give them the tools they need to combat piracy and other abuses.
We'll leave that to the federal courts to decide (we've heard they're good at that sort of thing), but Mike Masnick over at TechDirt nailed this one: basically Apple is getting sued because the tools they've been using to protect other people's intellectual property (namely that of the record industry) supposedly violate some other person's intellectual property.
Many executives and employees fail to see how these valuable tools can expose the organization to increased risk of data leakage and lost intellectual property.
