As a network security professional I can't stop laughing and crying at the same time.
Laughing because what he talks about is extremely oversimplified and exaggerated and crying because there are enough people who actually are paranoid enough to believe in this.
There is a big gap between what is theoretically possible and what is practically possible. After that there is another big gap between what is actually possible and what is actually done.
While such presentations shed a bit of light on the operations behind the scenes it is doing more harm than to actually educate people. It scares enough people to an extend that is influencing them more than the real surveillance threat.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
