By the actual design the amount of destroyed namecoins will decrease over time.
The total number of possible namecoins are 21 million - destroyed coins.
You can join to the Namecoin Forum and tell us if you are supporting the coin-destruction or the coin-lock(locked coins would be released when domain is released) solution.
Each solution has its advantage and disadvantage.
The ISP can block it but all ISPs over the world must block it otherwise some people still can access it.
But the .bit domain name cannot be confiscated like it can happen with usual domains. Confiscating .bit domains is like confiscating Bitcoins, it can only happen if you give them your private key.(or you transfer it to another address)
Coin destruction or coin lock: I think coin lock must be better so far but I haven't read enough about each option.
On censorship: I think that unless it is available to everyone then censorship has won. Only a few fringe uses having access to content would be terrible. In the UK there are basically 6 choices for broadband internet. A law affecting them could force these few providers into censoring internet and that would be it for the internet. Anti-censorship policies often miss this fact, assuming that censorship only happens by taking down a website. So I can't see how namecoin can possibly help if that's its purpose.
