The real heroes are the people that facilitate alternatives, not those who talk.
I know quite some people who live this way, and are very willing to overcome inconvenient hurdles to avoid having to use such a spying device.
To actually free yourself requires both commitment on your end and work on other people's end, those people who help facilitate alternatives and guide others to having more freedom and privacy. We need more of that work.
The speakers of the world have their place, of course, but that's not the most important part of the solution.
Such people both lead by example, and try to inspire others towards following their example/lifestyle. The problem rather is that most people want a different lifestyle (in the particular example of privacy and freedom "one with less radical consequences", which I consider to be rather contradictory, but this discussion shall be off topic).
To give an analogue: many vegetarians both lead by example, and inspire others to become vegetarians. But many people nevertheless don't want to become vegetarians.
