Bottom line is, it's good they're in China. . . . But there's a lot more they can do when it comes to thinking through the human rights implications of their business practices. If high-tech companies are serious about doing the right thing, they can join together and lobby for more transparency and accountability in the way in which Chinese officialdom deals with Internet services.

I must say I am not without sympathy for some of these executives, who find themselves in this position. It sounds like there are a lot of heated arguments going on in that [Microsoft] company.

Ultimately, if you're not behaving ethically, especially when it comes to information technology, especially when it comes to dictators, you are helping shape a world in which dictatorships are stronger.

What were the exact terms of the deals? Who made them? In what context did these conversations take place? I expect the revelations won't be too flattering for the companies concerned.

One day, people in China may be able to see the records of conversations between multinational tech companies and the Chinese authorities.

However, it seems that is never going to happen. So if people are going to filter, I want them to be open and transparent with their users about what they are filtering and why.

Nobody is one asking Western companies to go and lobby the Chinese government to change its behavior. That's not possible. But what we are asking companies to do is change the way in which they respond to Chinese government behavior and the way in which they interact with it, and that they can control.
