I very morbidly think that the uptake of #bitcoin and #nostr is directly proportional to the amount of pain people feel when interacting with the alternative systems that they're currently forced to use.
Freedom technology solves a problem that most people in privileged nations don't know they have because they're just in a light drizzle of piss and don't really mind as opposed to the torrential downpours experienced by literally everyone else.
It's the everyone else that will frontrun freedom technology at least in terms of numbers; people who know the problem and accept the solution. What gets those people on the new system is awareness, education, ease of use, experience, and familiarity. I think the most important aspect to preserve is the survivability of the protocol, because so long as it survives, people will adopt it and walk through a one way door of empowerment that they'll fight to keep using the tools they've been given.
