The only thing I'd possibly criticize is that he doesn't explicitly point out that the "secure systems for everyone" aren't really available due to deliberate steps by "those in power" to cripple "secure systems". His argument that there are more people who will do good with any given system than bad, isn't considered by those who consider the possibility of something "bad" being done with the system a reason to cripple and limit the system for all users.
Overall, I'll be recommending a bunch of non-techy people watch that quick video.
Edit: The BBC video is not loading for me
Also, I can't get the video to play past 2:01 unfortunately.
