I think a better argument is that between a third and a half of all people on Earth see enough value in some elements of social networks to sign up for them.

A lot of people I know only use Facebook for messenger. Some only use it for private groups. Some for events. Some for the newsfeed. Those people use twitter, instagram, whatsapp, snapchat, or discord for the features they don't use on Facebook.

IMO instead of looking for a service which could distribute the back-end servers of a single social network we should be encouraging the distribution of features, and make sure they can interact with each other smoothly.
