Is that your blog? I really don't think you've "caught him out" by saying his first paragraph contradicts his second. One paragraph is the present state of affairs, the other suggests future behaviour that can change the present state of affairs. Snowden doesn't have the luxury of communicating with people who have covered their tracks.

All of your bullet points thereafter merely describe the present state of affairs and do not in any way contradict the concept of using encryption to change them.

It's the defeatist attitude that I find the most defeating about this subject.
