The blogosphere is right, to be deeply unimpressed by Microsoft, Google et al, helping the Chinese government censor Chinese Blogs.
But I'm trying to remember the last time I read a story in the tech. media that went "we X.corp had a chance to do business in China, with certain restrictions, and we turned them down because it was against our principles." After which X.corp got lauded in the press. And gained huge amounts of free publicity.
The point is, actions like this are not noticed by the system. If we don't celebrate the companies that do the right thing, then how will they learn what the right thing is?
