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.
