Projecting from personal anecdote here, but... my social circles have almost no intersection with my life in tech. They are not "tech people". Yet I have only a single contact that still messages me via WhatsApp. Everyone else and all of the groups I'm in moved to Signal.

Mine too, but I think we’re uncommon. Far more people use WhatsApp than Signal.

On the plus side; existing familiarity with WhatsApp makes moving to Signal easy to understand for people as they are very similar apps.
