> Unless Signal brings social features that makes these people experience FOMO of broadcasting their lives on one more network
That's ultimately what it boils down to. Making an alternative messenger that people will use is one problem, but making one that people will use *instead* of WhatsApp is an entirely different beast. The former can be solved with new (non-privacy related) features, but that's not gonna be enough to overcome the network effect.
The really important question here is whether people really don't value their privacy that much or if they just don't know any better. If people really don't care, then there is no problem to be solved. If it's an uninformed decision, then this is not a technological problem but a societal one that can be solved with awareness campaigns for example.
Let's put it straight: majority of people don't give a damn on privacy. There should be a global pro-privacy campaign run by all of us to convince as many people as we can to respect their privacy!
