It's highly probable that the vast majority of users, and people in the future will recognize the Antminer / Blackrock pool as the legitimate Bitcoin instead of The Bitaxe / "Cypherpunk" pool.

While Bitcoin can be forked, and I hope that it is I don't think people, and entities like Michael Saylor, El Salvador, The U.S. government will recognize a Bitcoin payment system that poses a legitimate threat to institutions, and I don’t think most people will recognize The True Bitcoin Chain as legitimate either due to fear of arrest, or losing their fiat bags.
