If upsetting the hosts was a consideration then we should cancel Beijing. But is isn't so we shouldn't.
No, the real reason not to build anti-censorship schemes into the standards is that it is doomed to failure. From a technical point of view, there are three types of censorship. The first is the type the Internet is highly resistant to. It is not possible for any one country to dominate the Internet and control what is visible in the territory of another. The second is control of the borders of a territory. The third, control within a territory. The second two are something the Internet can't address as a structural issue. We can deploy a censorship-proof Internet in the parts where governments share our objectives. We do not dominate the Internet, we cannot force governments with counter objectives to allow deployment of the censorship-proofing technology. Counter-censorship within a territory where the censor controls the infrastructure requires tactical measures. The problem with tactics is that they only work so long as they are a surprise. With all due respect to MtFBwU, I would hope that he would want us to avoid giving away information to the opposition.
