Seems like most of these can be done without blockchain. Some are not even 'real world' at this point, but just experimenting. As others have pointed out, when in doubt - 'do you need a blockchain? no'. Overhyping them for use cases where they are not needed will have a negative effect on trying to get support for the places where they might actually be useful.
Exposing US surveillance of US citizens is clearly whistleblowing and a good thing. Taking government laptops with NSA information, telling the Chinese what sites of theirs the NSA hacked, and then releasing information about NSA listening in on others (outside of the US) goes well into the realm of breaking the law and should have consequences. Of course, taking a tour of our adversaries doesn't help his cause much...
Also, I find it hard to swallow those who are up in arms about NSA spying on non-US citizens... seriously??? What do they think the NSA was formed to do??? That should not be a surprise...
I do worry that Wikileaks is pretty much hijacking his agenda and substituting their own...
