But that doesn't fit with this example, the minority here is definitely ppl who switch to signal or want to use Signal as their main communication app.
Talebs arguments are more fitting in instances in which the cost of providing a different solution for a minority is too high and the cost (for some central provider) of just complying with minority demands for everyone is lower. Doesn't apply here at all.
I was referring to the friend who refused to leave WhatsApp not the broader global effect of migrating to Signal. For small group sizes the minority group’s preference will vary.
