Public Citizen vs. the Dallas Morning News
Public Citizen is a little rabid in its defense, saying that banning deep linking would destroy the Internet. That's true, but there's a much easier way to look at it. A deep link is like the phone number of an employee in a large corporation. If someone publishes that phone number, you have a right to print it, or to call it. The company has the right to change the number or not to answer it.
If the DMN doesn't like deep linking, it can use WebObjects or some other unfriendly technology that frustrates static links for individual pages. If the site chooses to give its pages links that always point to that content, then just like a corporate phone number, you're free to use them however you want. You're also free not to link to the paper at all, as this item does not.
