As I remember it, the Rexit that caused Voat to become so large was primarily composed disenfranchised conservatives, trolls, and those with extreme views. Even moderately conservative users were likely to feel out of place on Voat.

This Rexit seems primarily composed of disenfranchised mods, app users, and content producers. In my opinion, the much larger variety of people swapping to the Fediverse give it a much more stable base.
