This NYT article about Google's business in China bears reading, for several reasons.
1) It shows some unnapreciated cultural difficulties in working there.
2) It gives a balanced picture of some of the journalists that have been arrested for their blog posts. They're not martyrs for the cause of democracy, not like earlier generations of Chinese activists.
3) It gives a more sympathetic reading towards Google in the China/Free Speech issue. Namely, that Google offers two websites for Chinese surfers, one inside the firewall that gives back results that are clearly censored, and the basic google.com site outside the national firewall that can be blocked by China, at any given moment, but does offer free information.
4) Yahoo and Microsoft look unprincipled in comparison to Google.
After reading the piece, Google isn't behaving any differently than an Evangelical missionary in China. They have an official job (like teaching English, or giving censored search results). But they're willing to go other places for those who ask (share the Gospel, or provide access to google.com). I don't really see any fault here.
