According to this article, the chattel laws have been used to shut down freedom of speech. A court has ruled that it is ok for an individual to be sued for sending "unwanted" e-mail to corporation employees. It should be noted that this "unwanted" e-mail is not e-mail that the employees didn't want, but e-mail that the corporation didn't want the employees to see, because it criticized the corporation. Even more disturbing than this, chattel laws have been used to stop competitors from gathering information for comparative pricing from competitor's websites. These types of things threaten the very fibre of the internet, which fundamentally relies on free linking, not requiring a web-owner's permission to link to his site, or any sub-site within it. This is what makes the net efficient and useful to users.
