As a counterpoint imagine instead if the cost of messaging went from $50 million per year to the even more lean $0 per year. Messaging operations are expensive because they need servers to route your traffic. They need to route your traffic to navigate around the restrictions of IPv4 NAT. In a world of IPv6 there is no NAT (but firewall restrictions still apply). I have created a relationship model that solves for privacy without need for third party servers and then routes messages based upon that model, but it’s limited by IPv4.
