All censorship schemes impact speech beyond the category they were intended to restrict, but these bills are particularly egregious in that regard because they cause entire domains to vanish from the Web, not just infringing pages or files. Worse, an incredible range of useful, law-abiding sites can be blacklisted under these proposals. In fact, it seems that this has already begun to happen under the nascent DHS/ICE seizures program.

Censorship of Internet infrastructure will inevitably cause network errors and security problems. This is true in China, Iran and other countries that censor the network today; it will be just as true of American censorship. It is also true regardless of whether censorship is implemented via the DNS, proxies, firewalls, or any other method. Types of network errors and insecurity that we wrestle with today will become more widespread, and will affect sites other than those blacklisted by the American government.

The current bills — SOPA explicitly and PIPA implicitly — also threaten engineers who build Internet systems or offer services that are not readily and automatically compliant with censorship actions by the U.S. government. When we designed the Internet the first time, our priorities were reliability, robustness and minimizing central points of failure or control. We are alarmed that Congress is so close to mandating censorship-compliance as a design requirement for new Internet innovations. This can only damage the security of the network, and give authoritarian governments more power over what their citizens can read and publish.
