Social features do not make a social network. Maybe it’s just where I cycle (Northeast and Northwest USA) but approximately 100% of the people that I ride with post their rides to Strava. That is what makes it a social network.
Further, all of the alternatives that you listed have limitations that prevent them from being viable alternatives to Strava even if people were interested in migrating. Mainly these are related to device integration.
