although the explanation is technically correct but it is a terrible one because it is misleading.
all of these coins should be referred to as
bitcoin copies instead of bitcoin forks. and the term fork should only be used when the same project is being upgraded with a new rule or has a rule removed.
so for example bcash is not a bitcoin fork, it is a bitcoin copy.
BSV is the only relevant chain, cause it is the refactored original protocol that is the legal and stable true BitCoin.
3 bullshits in one sentence.
bcashsv is not relevant and it has not refactored anything and it is considered a shitcoin by literary everyone.
last time i checked bcashsv had BIP-143 (yes that is a SegWit BIP!!!) still implemented, and also since you mentioned "original protocol" it also has BIP62 and at least 2 dozen other BIPs still intact.
a long list of meaningless changes doesn't make it "original protocol".
