Red Hat, the world's largest, most successful open source software company and one I'd like to work for in the very near future, submitted this blog post last month about SOPA and PIPA. It explains how such bills could devastate online collaboration, innovation, and the sharing of ideas and technology.
This article talks about an alternative to SOPA and PIPA written by Reddit users. There's a link to the Reddit community and Google document they're working on. Although it's difficult for me to see how this document could impact/influence any actual legislation, redditors have had some success making waves in the past. After GoDaddy announced its support for SOPA, Reddit users staged a boycott. GoDaddy ultimately changed its position.
