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!
