I don’t really think those people would join fediverse tbh mostly because lack of algorithm driven feed, Twitter or X is for now center for new trends going in the world will it be political or is influencer drama, compared to X fedivese lacks many things that is needed to support needs of X users, also take in consideration that X is basically main social media many influencers and politicians and so on use to post updates and such and many people are using X for just that. As far as I know there is no verification checkmark on fediverse so it’s gonna be hard to get influencers here (which I don’t really even want to tbh), so they will probably move to bluesky or threads
