There's only one way out of this moral quicksand: A clear and consistent set of principles for what U.S. tech companies can and can't do in China... Jonathan Zittrain, a professor at the Oxford Internet Institute in England...sees three broad themes: • Transparency. Companies operating in repressive countries should always disclose what they're doing, including...what restrictions they are imposing on users. • Non-collaboration. Companies should not actively participate in acts of repression... • Gentle resistance. Companies should interpret restrictive rules as liberally as possible, thereby challenging attempts to scare them into self-censorship.
