Michael Geist sez,
While there is little that people living outside the U.S. can do to influence SOPA and PIPA, there are many reasons why it is important for everyone to participate in tomorrow's SOPA protest.
First, the SOPA provisions are designed to have an extra-territorial effect in countries around the world.
Second, non-U.S. businesses and websites could easily find themselves targeted by SOPA. The bill grants the U.S. "in rem" jurisdiction over any website that does not have a domestic jurisdictional connection.
Third, millions rely on the legitimate sites that are affected by the legislation. Whether creating a Wikipedia entry, posting a comment on Reddit, running a WordPress blog, participating in an open source software project, or reading a posting on Boing Boing, the lifeblood of the Internet is a direct target of SOPA. If non-Americans remain silent, they may ultimately find the sites and services they rely upon silenced by this legislation.
Fourth, the U.S. intellectual property strategy has long been premised on exporting its rules to other countries. SOPA virtually guarantees that this will continue.
