I don't know about that, but mostly because I consider the Bitcoin Foundation to be terminally corrupted and broken (and Bitcoin itself in a similar danger.)

If Snowden felt it important enough to weigh in on the risks facing the Bitcoin protocol and related technologies, and schemes which may be effective at dealing with attacks, I'd certainly listen to what he has to say.

At this point I think the most important thing is to retain the general concept that privacy and the ability to communicate freely is a natural human right.  As long as that principle is in place things will be OK.
