The english pages at Wikipedia.org will be blacked-out as a protest against proposed legislation in the United States – the Stop Online Piracy Act (SOPA) in the U.S. House of Representatives, and the PROTECT IP Act (PIPA) in the U.S. Senate – that, if passed, would seriously damage the free and open Internet, including Wikipedia.
Wikimedia Foundation board member Kat Walsh recently wrote
We depend on a legal infrastructure that makes it possible for us to operate. And we depend on a legal infrastructure that also allows other sites to host user-contributed material, both information and expression. For the most part, Wikimedia projects are organizing and summarizing and collecting the world’s knowledge. We’re putting it in context, and showing people how to make to sense of it.
But that knowledge has to be published somewhere for anyone to find and use it. Where it can be censored without due process, it hurts the speaker, the public, and Wikimedia. Where you can only speak if you have sufficient resources to fight legal challenges, or if your views are pre-approved by someone who does, the same narrow set of ideas already popular will continue to be all anyone has meaningful access to.
The Wikipedia english language pages should be back up by 4pm (AEDST) Thursday.
