Well Andrew Torba (the owner of Gab) highlighting this story to deride his competition may give you a bit of a clue.

Poa.st an instance of the Mastadon/Fediverse is interesting. It has its own feel outside of the Gab paradigm. It’s generally has a more insightful group of folk and less Nazi LARP/ Christian Nationalist rhetoric. Conversely they have antiFa trying to dox folks and an instance owner willing to dox unruly users. Each has its own pressures.
