Thanks, Jonathan, for a more comprehensive statement of your position. (See JZ's reply to my August 6 post)
If I may summarize your rejoinder, you make the following points: 1) Too much time is spent on ICANN, diverting scarce time and attention from more important venues; 2) Censorship of public labels would have “near zero effect” on access to content; 3) We are guarding the wrong door, the strongest threats to freedom of expression come from private firms, such as Google or Myspace or ISPs.
I pretty much disagree with all of them, although your point number 3 raises some intriguing issues and I simply may not understand where you are going with it.
