I was pleased to find this today: a letter written by the EFF that was sent to the U.S. House Subcommittee on Africa, Global Human Rights, and International Operations, who held hearings last week on the topic, "The Internet in China: A Tool for Suppression?" The letter addresses the moral concerns of doing business in China with provides some practical guidelines. In short:

1. Limit Data Collection and Data Retention
   With the stakes so high in countries like China, no Internet company should gather more information than they absolutely need about their customers and no Internet company should keep that information any longer than is absolutely necessary to provide the requested service.
2. Increase Transparency and Bear Witness
   Whenever and wherever possible, Internet companies should note when websites have been removed or search items filtered away, and explain under what power the government forced them to act to remove content or hand over data.
3. Don't Do Direct Business with Forces of State Oppression
   Companies should be prohibited from providing intentional ongoing support and assistance to those who abuse human rights in foreign countries.
4. Offer Opportunistic Encryption with Internet Services
   Internet companies like Google have easy technological shifts they can make to protect their users in repressive countries. One of the greatest gifts for evading surveillance and censorship online is built into every web browser: strong, near unbreakable encryption of web traffic.
5. Support Technologies that Innovate Around Censorship and Surveillance
   By working together on ways to surmount Internet control they will not only be providing wanted new products to 1.3 billion new customers, they will help open trade and communications between all countries, and all citizens.
