How it spread
Trace the originWhatsApp's terms notice prompted public calls to switch. Musk endorsed Signal, which topped app charts and struggled with signups and an outage. January daily-download estimates placed the high in mid-month; adoption slowed afterward.
Proxy date; not a directly measured attention peak. Some dates are known only to the week, month or year.
