Pop cultures change think beatles to punk two different worlds whats cool now won't be later. Will people care about a mission (currently no not at all at least in the west) of free speech depends on how culture changes and perception of the false reality built up that there is freedom in speech. It wont happen overnight and I don't believe it will be used unless and system is good ux/ui ease convenience but what we are seeing and the rate of building to that area is certainly promising!

Sure but even punk was kind of a subculture. I would be very surprised if free speech, privacy and decentralization would suddenly be seen as cool. Hope to be proven wrong of course.
We might live to see the day! Perhaps all I am saying rather than a dogmatic you're wrong I am right is being on the side of optimism leads to a greater possibility of seeing that which we would like to in the world at least partly as optimism promotes encouragement and therein awaits possibilities friend.
