The idea is that anyone can timestamp "leaks" which can be inserted into a chain for anyone to see.
Perhaps a percentage of the coin generation goes to wikileaks or openleaks for them to monitor the chain for these leaks.
It would be hard for governments to take it down and it would be transparent which is the whole point. I wonder if bradley manning would be not in jail today if he had this ?
Wikileaks take great care in removing any identifying marks from leaked documents, they don't just get stuff and publish stuff. This would remove the de-identifying work so leakers would have to do this themselves.
Perhaps a charity client with addresses built in you can donate too like wikileaks would be better.
Sometimes I forget bitcoin is only pseudo-anonymous.
