I think things get murky with complex relationships that exist in industry. For example, I think it would be hard to argue that a company like Expedia or Priceline created a feature so their customers (hotels) could exploit it. Also, what leverage do you think a developer has in these sorts of situations? Should the developer say they're not willing to write the feature because it's possible customers could exploit it?
