You’ll note that all of the discourse around Mastodon and Fediverse adoption now is about it “challenging” or “taking over” from Twitter.
This is yet another instance of pop culture taking over the discourse. Pop culture has to have a winner. It’s always a competition. Improvement or serving the end user is always secondary to winning out in a popularity contest.
Be extremely skeptical of any advice that is framed by the pop culture leaderboard. It’s likely to be toxic in the long run.
The fediverse doesn’t need to win over anything else. It does not need to challenge, threaten, or dominate any other community or service. All it needs to do is serve its existing members and be a good place for new people to join. Becoming a safer space is much more likely to contribute to its longevity than ‘winning’ mass adoption from ex-Twitter users in the short term.
