> The #fediverse must grow at least to a point it is long term sustainable
This.
A most crucial point. On a technical level marvelous work has been done, but what makes the Fediverse delightful are the socio-cultural aspects facilitated by the tech. These can only be cultivated, slowly and organically. And that took many years.
Grow too fast, and this culture will wither and die, to be replaced by same old same old corporate-controlled playgrounds. That is the current trend.
