You might be assuming that people interested in being on the fediverse have the goal of excessive reach. I acknowledge that some coming over from twitter might be interested in such a goal....but those individuals might simply not fully understand the compelling value that the fediverse (and mastodon instances) often represent. Not everyone wants/needs to reach 100M people.
- While, twitter (& other commercial socials) promise excessive/massive reach...The Fediverse might offer less, but richer interactions.
- While, twitter (& other commercial socials) promise users as cattle/"eyeballs" to ad buyers...The Fediverse offers none of that. (Though, individual instancves have every right and possibility if they
so choose to create their own ecosystem of ads to pay for their operations, and their people would need to know that of course)
- While, twitter (& other commercial socials) promise a platform for creators to publish their content to a wide audience...The Fediverse offers the same publishing (or better) capabilities and tools, but to a smaller audience...and, at least the existing creators on the Fedi are quite cool with that; most prefer it that way!
To me, living on the Fedi, is like people purposefully, willfully, happily (and not accidentally nor due to duress) moving to the rural country away from the big city...and not caring that others feel like "hey, the big city living is where everything is awesome" ;-)
