In this case, I suspect the biggest factor is simply having the right product at the right time. Twitter goes to hell and you've got a Twitter alternative ready to go? That's the perfect timing for a successful product/service.
It's no surprise that things like Hive, Mastodon and Cohost have exploded in popularity recently.
Of course, whether these products will be the ones that do well in the long run is still an unanswered question. Hive's security issues and temporary shut down came at the exact wrong time, Cohost's invite system is probably crippling it and people are still not 100% sure how to use Mastodon in some cases, so only time will tell which if any takes off.
