There is no incentive for Calvin Ayre (the benefactor behind Craig Wright, nChain and BSV) to support a mere fork. There is no incentive to support the whole Satoshi scam which is getting pretty expensive with all the lawsuits. The main reason behind the Satoshi scam is to justify the upcoming UTXO manipulation ("Satoshi is getting his coins back"). Shit's gonna be epic and there are breadcrumbs all over the place.
